Around 37–39 months, many children feel like chatty little planners: they may run and climb with ease, use short sentences to share plans and memories, play longer pretend games with toys or friends, and proudly insist “I do it myself!” as their independence and social world rapidly expand.

• By 37–39 months, many children eat the same basic meals as the family, with foods prepared in safe sizes and textures, and they often enjoy sitting at the table, using a small fork or spoon, and drinking from an open cup with only a little help.
• Strong ideas about food are very common now, such as wanting the same breakfast every day, refusing a food because it touched another food, or suddenly rejecting something they used to enjoy, so many parents focus on calmly offering a variety of nutritious choices over several days rather than pushing each bite.
• Letting your child help with easy jobs, like washing fruit, sprinkling cheese, stirring safe mixtures, or choosing between two healthy snacks, can turn meals and snacks into relaxed learning time for independence, coordination, and early conversation.

• Many children around 37–39 months still need a long stretch of sleep at night and may or may not have a daytime nap, and some families notice this is the stage when naps become shorter, less regular, or start to fade.
• A familiar bedtime pattern, such as a calm tidy-up, wash, pyjamas, a simple story, and a cuddle, often helps children shift from busy play into rest and gives a clear signal that the day is ending, even if they try to bargain for “one more story”.
• As imagination grows, some children start talking about dreams, shadows, or noises, so many families use gentle reassurance, a favourite comfort item, and low light, while keeping night-time mainly for soothing and sleep rather than long chats or new games.

• Between 37 and 39 months, some children are still in nappies or pull-ups, some use them only at night, and some are mostly using a potty or toilet in the daytime, so there is a wide range of toileting stages at this age and change often happens gradually.
• Many children show clearer signs that they are about to wee or poo, such as pausing their play, crossing their legs, or telling you they need to go, and families often use these moments to offer a relaxed trip to the potty or toilet without rushing or pressure.
• Talking simply about wees, poos, and wiping, using the same easy words each time, praising tries, and keeping changes calm and matter-of-fact can help build confidence, even while accidents and spare clothes are still a normal part of many days.

• Short, regular playtimes through the day, such as 5–10 minutes of building tall towers, matching pictures, doing simple puzzles, threading big beads with help, or drawing circles and lines, give many chances to practise problem-solving, hand control, and early planning skills.
• Several times a day, you might chat together about what you see, count small groups of toys or steps, talk about colours, sizes, and simple feelings, and enjoy picture books with repeated phrases, which supports language, early number sense, memory, and listening in a playful way.
• Daily active play, such as dancing to a few songs, playing chase or ball games, stepping over cushions, jumping off a safe low step into your arms, or joining in “ready, steady, go” activities for a few minutes at a time, helps build strength, balance, social skills, and the joy of moving their growing body while they learn to follow simple instructions and take turns.
