Watch for these milestones to occur between 18-24 months.

Understands but Might Not Follow Instructions
You tot understands when you give instructions, though she may follow the directions or run off gleefully without a second thought. Is she being deliberately disobedient?
Stop Putting Objects in Mouth and Identify Body Parts
You may notice your child moving beyond the sensory and exploratory habit of putting everything in her mouth--and instead find she can identify her mouth (and maybe nose and eyes, too)!
Undress by Himself
For your tot, getting out of his clothes by himself is a developmental milestone. Once he's figured out how to undress, don't be surprised if you catch him with nothing on!
Speak Well Enough to be Understood
You may be doing less interpreting of your toddler's speech these days. Around this age, little ones often begin speaking well enough to be understood much of the time.
Identify People/Objects in Pictures
The pictures in your family's album take on new meaning to your growing tot. Ask him to point out loved ones in photos--he's learning to identify familiar people and objects.
Can Walk Down Stairs
No longer content to descend on his hands and knees, your child may venture into walking down the stairs. Be sure he's supervised as he practices this large-motor skill.
If you remove a toy from your kiddo's sight, he understands that it still exists and may try to find it. You can test his sense of object permanence with a game of hide-and-seek!
If you tell her the ball rolled under the table, does your little one know where to look? Under, over, up and down--your child is grasping the meaning of prepositions.
Starts "Mine" Routine With Objects
It's a toddler's motto: What's mine is mine, and what's yours is mine! Watch as your sweet little one suddenly becomes possessive over every object that passes through her hands.
A stash of blocks can provide lots of entertainment for a toddler--especially once she becomes proficient at stacking them. It's fun to build a high tower and send it crashing!
Wants Attention All the Time
It's in a toddler's nature to want a parent's attention all to himself, all the time--leaving Mom and Dad to cope with constant interruptions and demands. Learn more about this common, attention-seeking behavior.
Identifies Likes and Dislikes
Your child may cherish her yellow pajamas--until tonight, when she emphatically announces she doesn't want them anymore! Watch as your tot learns to express her likes and dislikes.
Names Body Parts
Head, shoulders, knees and toes...how many body parts can your kiddo name? Make a game out of pointing to each other's elbows and ears!
