Your 18-Month-Old’s Development and Milestones
At 18 months old, your toddler may be growing more and more independent and even a little feisty—they may even start saying “no” more often to things you ask them to do. You might notice that they’re getting better at walking up and down stairs and coordinating the use of their hands and fingers now that they're 1 and a half years old. Read on for developmental insights and advice that may be helpful this month, and to learn what else might be in store!
Toddler Development Milestones
Every child is a unique individual, developing at their own rate, so your 18-month-old toddler may reach these milestones either this month or a little earlier or later:
Activities for Supporting Your 18-Month-Old Toddler’s Development
Searching for things to do with an 18-month-old? Here are some ideas for play, learning activities, and outings that can help support your 18-month-old’s development:
Mealtimes and Menus for Your 18-Month-Old
You may be noticing that your toddler’s eating habits are quite unpredictable. One day, they might eat everything in sight, and the next, they may turn down anything you offer them, even a food that was once their favorite. It might give you peace of mind to know that your 18-month-old is not unique in this behavior.
Most toddlers around this age have fluctuations in how hungry they are depending on things like their level of activity that day, their metabolism, and whether they’re in the middle of a growth spurt. If you’re concerned about your 18-month-old’s eating habits, consult their healthcare provider, who may have tips on picky eating or recommend vitamins for your toddler.
Most children do well with three small meals and two snacks per day. Serve a variety of nutritious foods and let your 18-month-old choose what and how much of it to eat. You’ll find that, over the course of a few days, their diet will naturally balance itself out so they get all the nutrients they need.

Limiting Sweets
It’s natural for your little one to prefer sweets over other foods. You may have noticed when feeding them baby foods that they gobbled up the sweet options, like carrots or sweet potatoes. Now that they’re a toddler, they would most likely pick a cookie over a piece of cheese if those were offered.
As their parent, you’re in control of the food served to your toddler, and it’s important to encourage healthy choices and limit their intake of sugary food. Even if they refuse dinner, don’t give in and let them have sweets just because they’re not eating.
Your 18-Month-Old Toddler’s Sleep Schedule
You may be wondering how long an 18-month-old “should” sleep and nap. At 18 months old, your toddler typically requires between 12 and 14 hours of sleep a day, including one nap per day.
If your toddler is in day care, the facility often has one or two nap times scheduled each day. You may want to check in with the day care staff to find out how well your child is napping. If you notice your child is overtired when you pick them up from day care, it could be because these nap times are not productive. Ask the staff what could be done to improve the situation and how to better coordinate your toddler’s sleep training at home and at the day care facility.
To help you keep track of your 18-month-old toddler’s nap and sleep schedule, Pampers created the Smart Sleep Coach app. Co-created by pediatricians and sleep experts, this app can make it easier to stick to a bedtime routine, assist with sleep training, and help you manage sleep regression if it arises.

FAQS AT A GLANCE
Are you asking yourself “What ‘should’ I expect from my 18-month-old?” Remember that every child is unique and that their development won't necessarily be the same as that of another child of the same age. However, during this month, or sometime soon, your toddler may be able to do things like:
- Scribble and draw
- Follow simple instructions that you give them
- Point to familiar objects that you name
- Speak using simple phrases
- Sort shapes and colors.
Your Life as a Parent: Setting a Good Example
Around this month, your toddler may start imitating you and your partner more and more. They might see you talking on the phone, and they’ll do the same with their toy phone, or they’ll try to drive their toy car after seeing you at the wheel. Since their inclination to imitate is so strong during this time, it’s a good idea to be on your best behavior, too, so you can set a good example.
Here are some ways to model good behavior for your toddler:
Checklist for This Month
□ Schedule and go to the 18-month checkup. Your toddler’s 18-month appointment is an important one, as there’s so much going on. This is a good opportunity to raise any questions like “How many words ‘should’ an 18-month-old say” or “How much ‘should’ an 18-month-old weigh.” So come prepared with a list to get all the answers at the checkup. At this visit, your child’s provider will check your 18-month-old’s overall growth, weight, and height; do a physical exam; and order any tests and provide any vaccines that your child may need. Your provider will go over common issues at this stage of development, which could include diet, discipline, and sleep.
□ Schedule a trip to the dentist. If you haven’t already done so, schedule your toddler’s next dental visit. It’s a good idea to have regular checkups every six months, unless your child’s dentist or healthcare provider recommends otherwise. At the visit, the dentist will make sure your toddler’s teeth are coming in and developing in a healthy way and may give you personalized advice on dental hygiene. Seeing a pediatric dentist is recommended by the American Academy of Pediatric Dentistry (AAPD), but if that’s not possible, look for a general dentist who has experience with children.
□ Start a scrapbook. As your toddler does more arts and crafts activities, like drawing, finger-painting, or simply scribbling with crayons or colored pencils, it might be time to start a scrapbook to save some of the artwork.
