All about your 15 month old
Vocabulary expands, picky eating is common, and some toddlers are down to one nap.
Read the guideSixteen months is the “I do it” month. A crayon makes its first real marks, a toddler wants to climb into the chair without your hands, and naps can turn into a debate. Many families are on one midday nap now, or nearly there. Independence is the skill. Frustration is the side effect. Your job is to offer safe ways to try — and a schedule that still includes rest they will not vote for.

At 16 months, many toddlers do well with 13–14 hours of total sleep: 10–12 hours at night and 2–3 hours during the day. Plenty have moved to one nap. Some still need two. On a one-nap schedule, wake windows stretch to about 5–5.5 hours before the nap and 5–5.5 hours before bed. The remaining nap often starts short and then lengthens toward 2–2.5 hours once the body trusts the new rhythm.
Nap resistance at 16 months is frequently independence wearing pajamas. They can climb, stand, and have a point of view about lying down. Pesky molars, separation feelings, and a nap that is still timed like a two-nap day can all pile on. If they are not sleepy at the old morning nap time but fall apart before dinner, they likely need the nap later, not abandoned. A consistent lights-out window helps more than bargaining in the doorway.
Longer bedtime wind-downs are common. Keep the routine to a handful of steps in the same order — wash, pajamas, two books, lights down — and end it even if they protest the last page. Climbing practice belongs on the couch cushion during the day, not as a new crib sport at 8:00 PM. If they are taking more than 30–40 minutes to fall asleep and are cheerful the whole time, they may need a slightly longer last wake window.
Many 16 month olds are on one nap with about 5–5.5 hour wake windows. This sample uses a 7:00 AM wake. Shift lunch before the nap so hunger does not end it early.
Independence, molars, and a nap transition can make sleep look bumpy for a stretch. Consistent timing still helps more than a brand-new method every night.
Scribbling is a real 16-month milestone, not just a mess on the table. After months of watching you make marks, many toddlers start making their own — a jab, a scrape, a wild loop. That is fine-motor work, cause-and-effect, and early writing all at once. Tape paper down, offer chunky crayons, and skip the quest for a drawing that looks like something. The point is the mark.
Walking, if it has arrived, is getting more automatic. Some toddlers walk backward, tow a toy, or take stairs on all fours or with a hand held. They try utensils and cups with more intent. Stacking two blocks, finding a toy they watched you hide, and attempting a problem before calling for you — dumping the wrong shape, then another — are the cognitive story. Two-word combinations may be understood even if they are not said yet.
Independence has a volume knob that seems stuck on high. They want to put on the shoe, hold the keys, press the elevator button. When the skill does not match the wish, tantrums show up. Separation anxiety can also peak again around 15–18 months. Routines help: the same goodbye, the same nap song, the same chair at dinner. Give jobs that are truly doable so “I do it” sometimes ends in success.
Scribbling and “I do it” are hallmarks this month. Ranges are wide. Trust your instincts and call your pediatrician if skills reverse or something feels off.
Sixteen-month-olds still run on three meals and two snacks, about 2–3 hours apart, with roughly 16 oz of whole milk or a fortified alternative. Appetite can look wildly uneven: a huge breakfast, a theatrical lunch refusal, a snack that saves the afternoon. That pattern is common once growth slows. Balance across the week matters more than a clean plate at noon.
Independence at the table means more mess and more skill. They want the spoon, then eat with fingers anyway. They want to climb into the chair, then need a strap for safety. Let them practice, keep portions small so “all done” can happen without waste wars, and avoid turning meals into a show. You are still in charge of the menu. They are in charge of their stomach.
Picky streaks continue. Keep offering the refused food in different shapes — steamed, mashed, with a dip they already like — without a speech about nutrition. If milk sips fill the gaps, solids will look worse. Offer milk with meals, water between, and a protein-containing snack before a one-nap stretch so hunger does not cut sleep short.

Common questions parents ask at the 16 months stage.
Yes. Making marks on paper is an expected fine-motor and cognitive step in this stretch — CDC lists scribbling by 18 months, and many toddlers start sooner. You are not looking for a drawing of a person. A jab, a line, or a scribble after watching you counts. Offer paper and chunky crayons, and sit with them so the crayon stays on the page more than the wall.
They can imagine doing the whole job and cannot yet zip, pour, or explain. That gap is the tantrum. Offer pieces of the task they can finish, give two choices, and name the feeling. Independence is not a discipline problem. It is development, and it needs safe practice more than a lecture.
If two naps still happen without a painfully late bedtime or night-sleep collapse, you can stay. Many 16 month olds have already moved to one nap with 5–5.5 hour windows. If the morning nap is a fight and the afternoon is the one they can still take, shift toward a single midday nap and pull bedtime earlier until it lengthens.
Build the meal for fingers and a practice spoon, strap the chair, and sit down with them. Serve a small amount, then more. You choose the food; they choose the quantity. If the meal is over, it is over — a planned snack later is calmer than a 40-minute chase with a fork.
