18-Month-Old: Confident and Independent
At 18 months old, your toddler is reaching new milestones, such as growing more independent. This new sense of self may translate into some stubbornness, and you might hear the word “no” a lot more often! You may also notice some improvement in walking, stairclimbing, and hand and finger coordination. Read on to learn more about these 18-month-old developmental milestones and what else is in store as your child turns one and a half years old!
Toddler Development: 18-Month-Old Milestones
Every child is a unique individual, developing at their own rate, so your 18-month-old toddler may reach the following milestones either this month or a little earlier or later:
How to Support Your 18-Month-Old’s Development Milestones
These are many activities for 18-month-old toddlers that help support their development milestones, including the following:
Mealtimes and Menus for Your 18-Month-Old
You may be noticing that your toddler’s eating habits are quite unpredictable. One day, your little grazer may eat everything in sight, and the next, they may turn down anything you offer, even a favourite food. It might give you peace of mind to know that your toddler is not unique in this behaviour! Most toddlers around 18-months-old have fluctuations in how hungry they are depending on things like their level of activity that day, their metabolism, and whether they are in the middle of a growth spurt. Most 18-month-olds do well with three small meals and two snacks per day. Serve a variety of nutritious foods and let your child decide 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 to provide all the necessary nutrients.
Limiting Sweets
It’s natural for your little one to prefer sweets over other foods. You may have noticed when feeding your child baby foods, they gobbled up the sweet options, like carrots or sweet potatoes. Now that your baby is a toddler, they would most likely pick a cookie over a piece of cheese, if offered. As the parent, you are in control of the food served to your toddler, and it’s important to encourage healthy choices and limit the intake of sugary food. Even if your child refuses dinner, don’t give in with sweets just because they’re not eating.
18-Month-Old Sleep Schedule and Sleep Regression
At 18 months old, your toddler’s sleep schedule typically requires between 12 and 14 hours of sleep a day. Included in this number is one nap per day.
If your toddler is in daycare, the facility may have one or two nap times scheduled each day. You may want to check in with the daycare staff to find out how well your child is napping and ensure your 18-month-old’s sleep schedule isn’t disturbed too much. If you notice your little one is overtired when you pick them up from daycare, 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 routine at home and at the daycare facility. If you notice your 18-month-old experiencing any sleep regression, it could be a mix of over napping during the day and too much excitement on the mind. When children development new milestones and gain fun skills, they don’t always love pausing that excitement for naps or nightly sleeps!
A Day in the Life of Your Toddler
Here’s a snapshot of what your 1-and-a-half-year-old’s day might look like:

Your Life as an 18-Month-Old’s Parent: Setting a Good Example
Around this month, your toddler may be starting to imitate you more and more. Your child may see you talking on the phone and do the same with their toy phone, or they’ll try to drive their toy car after seeing you at the wheel. Since your 18-month-old’s inclination to imitate is so strong during this time, it’s a good idea to be on your best behaviour, too, so you can set a good example. Here are some ways to set a good example for your 18-month-old toddler:
FAQs AT A GLANCE
During this month, or sometime soon, your toddler may be able to do things like:
- Scribble and draw
- Follow simple verbal instructions
- Point to familiar objects
- Speak using simple phrases
- sort shapes and colours
Remember that every child develops at a unique pace, so there’s nothing set in stone regarding what an 18-month-old “should” be doing exactly, and your toddler may exhibit these milestones earlier or later.
