21-Month-Old: Your Little Adventurer
Your toddler’s world seems to be expanding almost by the day as he or she gets better at walking, climbing and communicating. Read on to find out what speech and other milestones are in store this month and get some tips for great activities to support your 21-month-old’s development.
21-Month-Old Milestones
Your toddler is a character at this age, and you can expect every day to be an adventure as your 21-month-old learns to do new things, improves existing skills and reveals yet more of that adorable personality.
Though rates of development vary between children, here are some of the milestones that could be reached (or just around the corner) at 21 months old or thereabouts:
Fine Motor Skills: Pouring
You might feel you’ve already had your share of clearing up accidental spills, but don’t put that mop and bucket away just yet! Now your child is developing the dexterity needed to deliberately pour liquid or sand (or that delicious broccoli purée you just made) out of a container.
Your toddler can have endless fun mastering this ability – for example in the bath, tipping water out of cups onto a water wheel or similar bath toy. Channel this new skill and get your little one involved in cooking by measuring out liquid ingredients into cups and so your budding chef can pour them into the mixing bowl for you.
Movement: Poise and Balance
Your 21-month-old’s sense of balance is improving all the time. Around this time, you may notice your child standing on tiptoes to reach for objects on high shelves. If this brings any potential hazards – such as cords and heavy or sharp objects – within range of those curious fingers it might be time to double-check your home’s baby proofing again.
Other signs of your toddler’s developing sense of balance could include:
Visual perception: Hide and Seek
Around this age, your toddler may be able to remember where things are hidden, so hiding games can be great fun for a child of around 21 months old. Play ‘hunt the teddy bear’, taking it in turns to hide the bear and look for it. Or hide yourself/each other in a game of hide and seek. Your child may not fully understand the rules but will love the thrill of being ‘found’ or finding you behind the sofa.
Understanding Speech at 21 Months Old: Instructions and Questions
As your toddler’s speech continues to develop, it may start becoming second nature to start giving your child simple instructions like ‘get your shoes’. Ask basic questions like ‘where’s the ball’, and soon you could be delighted to see your 21-month-old pointing to the object (or picture in a book) in question.
And your toddler may be getting better at speaking too. The first simple sentences your little one speaks could just be a couple of words strung together, like ‘bring teddy’, but they’ll melt your heart all the same.
How to Support Your Toddler’s Development
Support your 21-month-old’s development with activities like:
Mealtimes for Your 21-Month-Old Toddler
A healthy, well-balanced diet is important to support your 21-month-old’s growth and physical development. Offer three meals and two healthy snacks a day.
Your toddler’s diet should include a healthy mix of the four main food groups:
Introducing New Foods and Flavours
The exciting thing about toddlerhood is that every day brings new experiences. Help those tiny taste buds develop by introducing new foods and flavours at mealtimes.
Experiencing a wide variety of different tastes and textures can get your child into healthy eating habits that might last a lifetime, so it’s never too early to offer your toddler a wide choice of healthy food options.
Here are a few ideas to make things more interesting at breakfast, lunch, and dinner:
How Much Sleep Does a 21-Month-Old Toddler Need?
Most toddlers at this age need 11 to 14 hours of sleep including at least 1 nap during the day. There’s plenty you can do to help your toddler get off to sleep more easily, such as keeping to a regular bedtime routine and making sure your child’s room is kept dark and at the right temperature.
Even if your toddler is usually a good sleeper, there might still be periods when he or she finds it hard to drop off or wakes up during the night. Young children’s sleep patterns change over time, and sleep can also be disrupted by upheavals such as moving to a new house or even just making the switch from a cot to a ‘proper’ child’s bed.
If your 21-month-old seems anxious at bedtime or wakes in the night and has trouble falling back to sleep, you could try the ‘kissing game method’ to help your toddler settle down to sleep.
A Day in the Life of Your Toddler
No two days are the same with a toddler in the house, but here’s what a typical day might look like with your 21-month-old:
Your Toddler’s Health: Skin Care
Many toddlers have sensitive skin, and skin problems can arise from time to time. Here are some of the skin issues your toddler may experience:
Only your child’s doctor can diagnose exactly what may be causing any red, sore, or irritated skin and advise on the best treatment. Still, there are a few things you can do to help prevent or remedy dry skin:

Your Life as a Parent: Worries About Your Child’s Development
It’s normal to occasionally worry about whether your toddler is developing at the right pace, or to wonder if there are any milestones all children are supposed to hit at 21 months old.
Keep in mind that every child is unique. Although it may be easier said than done, try not to compare your little one’s progress to other children's achievements and milestones. For example, don’t worry if your 21-month-old is not talking as much as a friend’s child of the same age. The same goes for comparisons between siblings, too – resist the temptation to measure your toddler’s development against that of your older child at the same age.
If you’re worried about any aspect of your child’s development, talk to your health visitor or your child’s doctor, who can provide reassurance and recommend any next steps that are needed.
