    42.From Losing Baby Teeth to New Teeth

    When children begin losing their baby teeth, parents often find themselves with a whole new set of questions. Why has one child already started losing teeth while another has not? How long should it take for a permanent tooth to appear? Why do the two sides of the mouth seem to change at different speeds? Why do new permanent teeth look so big, crooked, or crowded? And if a permanent tooth starts coming in behind a baby tooth, does that baby tooth need to be pulled? The transition from baby teeth to permanent teeth is not a perfectly synchronized process. During the early mixed-dentition years, timing, sequence, position, and appearance can all vary more than many parents expect. In this episode, we look at the normal biology of early tooth replacement, from loose baby teeth and permanent-tooth eruption to so-called “shark teeth,” asymmetry, early crowding, and orthodontic evaluation. We also discuss what parents can safely watch, how to handle a naturally loose tooth, why dental trauma is different from normal tooth loss, and which signs deserve a closer look from a dentist. The goal is not to judge every new tooth by how straight it looks on day one. The more useful question is whether the overall developmental process is still moving forward normally.

    41.How Children Learn to Find Their Own Next Step — Developing Autonomy

    Your child has a room full of toys—so why do they still come over and ask: “What should I do now?” This does not necessarily mean they do not know how to play, lack imagination, or are not independent enough. When no one provides the next step, children have to do something surprisingly complex: come up with possible activities, choose among them, get started, and then stay engaged long enough for the activity to take shape. In this episode, we explore how autonomy gradually develops in the preschool years. Why is choosing between two options different from generating an idea on your own?What might a child really mean when they say, “I’m bored”?Does unstructured time automatically lead to creativity?And when should adults step in with ideas, structure, or companionship? Perhaps the most useful question is not: “How long can my child play alone?” But rather: When no one tells them what comes next, how are they learning to turn an empty stretch of time into a goal of their own?

    40.They Can Do It—Why Do They Still Need Reminders? | Self-Regulation

    Your child knows how to get dressed, clean up, and prepare to leave the house—so why do they still need so many reminders? It is easy to assume that once a child can complete a task, they already know how to manage it independently. But if we slow the process down, we may notice something different: the adult is often the one noticing what is unfinished, checking for mistakes, deciding what should happen next, and prompting the action. The child may be doing the task, while the hidden work of managing it is still happening in the parent’s mind. In this episode, we look at the invisible regulatory work behind everyday reminders and explore how children gradually begin to take more of that work on themselves—checking, noticing, deciding, initiating, and correcting. We also discuss why true independence does not mean never needing help. Over time, children may begin to use checklists, environmental cues, and even other people’s reminders more intentionally. Perhaps the better question is not, “How many times did I have to remind my child today?” It is: Which parts of this task are starting to become truly theirs?

    39.They Remembered—So Why Did They Forget? — The Development of Prospective Memory

    When children sincerely agree to do something later, why does it sometimes seem to vanish from their minds when the moment actually arrives? And why can a simple reminder suddenly bring it all back? At the heart of this puzzle is prospective memory—our ability to remember to carry out an intention in the future. For preschool children, remembering what they are supposed to do and spontaneously recalling it at the right moment are not quite the same thing. In this episode, we explore what happens between “I’ll remember” and actually remembering later. From bringing a water bottle to putting away toys, we look at why young children can genuinely remember an intention yet still fail to retrieve it when it matters. Sometimes, what slips away isn’t the intention itself—it’s remembering to remember.

    38.Beyond Following Directions: How Children Begin to Plan Ahead

    If a five-year-old can follow directions—put on their shoes, grab a water bottle, brush their teeth, and get ready for bed—does that mean they already know how to plan? Not quite. Following a plan and creating one are two very different things. For young children, planning doesn’t begin with calendars, schedules, or carefully organized to-do lists. It starts much smaller: understanding that events have an order, beginning to think about what comes next, imagining a future need and preparing for it now, and gradually taking responsibility for one small part of everyday life. In this episode of The Scientific Parenting Diary, we explore how early planning abilities develop through event scripts, episodic future thinking, and prospective memory. Why can a child know the bedtime sequence—“brush teeth, read a book, turn off the light”—and still not be able to plan it independently? Why might a child sincerely say, “The water bottle is my job,” and completely forget it ten minutes later? Why can “check your bottle when we get to the door” be easier than “remember your bottle in ten minutes”? And what can children’s free play reveal about their emerging ability to set goals, organize steps, solve problems, and revise a plan? The goal isn’t to turn preschoolers into efficient little adults. It’s to gradually give them room to think, choose, prepare, remember, and take ownership of one manageable step at a time. Because perhaps the beginning of planning is simply the moment a child starts to hold a “next step” of their own.

    37."Fiver more minutes": why is it so hard for children to stop?

    Why do preschoolers keep asking for “five more minutes”—even when we have already warned them that it is time to stop? For young children, leaving the playground, putting away the blocks, ending a favorite activity, or settling down for bed is not simply a matter of listening or refusing to listen. A successful transition draws on developing skills such as attentional shifting, inhibitory control, cognitive flexibility, and emotion regulation. In this episode of The Scientific Parenting Diary, we explore why stopping can be so difficult, why countdowns sometimes help and sometimes do not, and how predictable endings, limited choices, and emotional support can make transitions easier. The hardest part may not be the ending itself. Children are still learning how to move from one world into the next.

    36.Beyond Hurry: Helping Children Build a Sense of Time

    Why do preschool children seem to slow down exactly when it is time to leave the house? And why does saying “hurry up” often make the morning feel even harder? In this episode of The Scientific Parenting Diary, we explore how young children develop a sense of time, why clock-based phrases like “five more minutes” can feel abstract to them, and why everyday routines place a surprisingly heavy demand on their developing executive function. From getting dressed to brushing teeth, finding shoes, and grabbing a backpack, what looks simple to adults can be a complex chain of memory, attention, sequencing, and self-regulation for a young child. Children are not born understanding time. Instead of repeating “hurry up,” we can help them by making time visible, breaking routines into smaller steps, and giving them a clearer map to follow.

    35.From Preschool to Kindergarten: What Should Parents Prepare?

    Around age five or six, many children move from preschool, daycare, or early childhood programs into a more formal school setting such as Kindergarten. To adults, this may look like simply changing schools. But for children, it can mean a major shift in daily rhythm, teachers, classmates, rules, routines, arrival time, and expectations for independence. In this episode of The Scientific Parenting Diary, we talk about what parents can prepare before a child moves from preschool to Kindergarten. This episode is not about teaching academic content early or creating school-entry anxiety. Instead, we focus on the practical and emotional foundations that help children enter a new school environment with more confidence: adjusting sleep and morning routines, practicing lunch box and water bottle skills, managing backpacks and bathroom routines, learning how to ask teachers for help, and building a mental map of the new school through routes, photos, and pretend play. Preparing for school is not about turning a young child into a little elementary student ahead of time. It is about reducing uncertainty, building familiarity, and giving children more security, energy, and confidence as they step into a new stage of school life.
