Feet Prepare for Walking: Two things happen ahead of your baby walking. One, they get pigeon-toed, which will improve their balance.

Both developments will fade as your baby begins to walk.

Now, with that practice, they’ll be more confident, so be sure to keep a close eye and keep the baby gate closed.

Hiding, Seeking, and Remembering: when your baby was learning about object permanence? Well, all they’ve learned and absorbed begins to show itself, no pun intended, when your baby starts playing hiding games, like hide and go seek, both with objects and themselves. Now that they understand things continue to exist when out of sight, they love to make things “disappear” and squeal with delight when they’re found!
Imagination Time! Many babies this age begin to play pretend. They’ll pretend talk on the phone, pretend cook, and pretend walk the dog – anything they see you do; they will pretend to do themselves.
Possessiveness Emerges: “Mine” will be a word that enters your baby’s vocabulary around now. This can lead to some selfishness – but this is easily correct with firm but gentle lessons on sharing.
Your 21-month-old still needs plenty of rest – keep them on track by following the 21-month-old sleep schedule .

A 24-Month-Old’s Developmental Milestones:
Happy 2 nd birthday to your baby!
A 24-Month-Old’s Communication Milestones:
Simple Requests: Your 2-year-old may make simple requests, such as “more milk.” This is a great time to teach your baby about please and thank you, too.
Blowing Kisses: Your baby may now blow kisses and make other “complex” gestures.
A 24-Month-Old’s Physical Milestones:
Playing Ball: By 2-years most babies can kick a slow ball.
Running: Wow! Less than a year after learning how to walk, most 24-month-olds run with confidence. Prepare to chase after!
Walking Up Stairs: A 24-month-old can walk up the stairs with better balance and confidence.
Knobs and Switches: Your baby will also become more interested in knobs, switches, and buttons. If you haven’t already baby-proofed your stove, now is the time.
A 24-Month-Old’s Emotional Milestones:
Empathy: Your baby now understands different emotions, including when someone’s upset. This helps them develop the power of empathy - watch as they exercise this empathy by trying to help soothe an upset friend or sibling.
Let the Tantrums Begin: A less exciting development - many 2-year-olds begin to throw tantrums, typically when they don’t get their way. This is “the terrible twos.”
Though they can be unsettling, tantrums are perfectly natural: they are feeling a lot of emotions they can’t always express. This results in a wave of frustration. Note: Tantrums are more likely if your baby is hungry or tired. Help prevent tantrums by making sure your baby is getting all the sleep they need for their age – something that’s easy if you use a tool like the Smart Sleep Coach by Pampers™ .
And review the 24-month-old sleep schedule to ensure your little one gets the rest they need.
How To Support Your Baby’s Development:
As your little one continues to grow, remember that they are a little individual who goes at their own pace. Fear not if your baby is still learning some skills; they’ll get there in time – especially if you use the Smart Sleep Coach by Pampers™. It will help you and your little one stay on top of their sleep – an essential ingredient to your baby’s long-term health .
