Remember when you first brought your baby home? If you’re like me, you suddenly found yourself Googling everything about baby development. You probably know the typical types of developmental milestones but what about those that often get overlooked?
Even though my background is in child development, the nerves and sleep deprivation of early parenthood left me with a foggy brain and dizzy with questions. All the parenting books and websites usually have the standard developmental milestones covered: rolling over, walking, first words, etc.

As a developmentalist, I began to notice that the smaller, more subtle types of developmental milestones are often overlooked in the parenting books. For example, remember the first time your child was able to hug you back when you hugged them? Or the first time they blew “raspberries” in such a silly way that you broke into laughter?
These overlooked milestones may not make it into the parenting books, but they mean the world to you. So I’ve compiled a must-have list of often-overlooked child development milestones to help you savor a few more aspects of your child’s development. These are often not apparent to some parents unless you know what to look for.
Most of these milestones are subtle because they have to do with your child’s cognitive development and changes in how they understand the world. These aren’t always easily seen, but if you observe closely, you might just see evidence of them.
5 Often-Overlooked Developmental Milestones in Young Children
Object Permanence: a child’s ability to know an object or person still exists even when it cannot be seen.
One clear sign that your baby has developed this skill is if they look for a toy that’s hidden under a blanket. This usually develops around 6-8 months of age.
The development of this skill sometimes coexists with an increase in separation anxiety. Since your baby now knows you still exist even when you aren’t present, they may protest or cry when you leave.
Theory of Mind: the ability of a child to understand the perspective or thoughts of another person.
When your child’s hasn’t yet developed Theory of Mind, they may do things like list their favorite food, color, etc. as your favorite. They do not yet understand that you have different thoughts than them.
This skill usually develops around age 3.5 to 4.
Recognize Self in a Mirror: a child’s ability to recognize that the person reflected in a mirror is actually herself, not another person.
This is one measure of self-awareness (although not the only one)
Typically, this skill is tested by putting lipstick on a baby’s face and placing her in front of a mirror. If she grabs at her own face to rub the lipstick, then it is thought that she has developed self-awareness.
This skill usually develops around 18 months of age.
Attachment to a comfort object: Although not all kids become attached to a “lovey” it is a common behavior that helps young children feel comforted and safe.
The attachment object can be almost anything—blanket, toy, stuffed animal, etc.
This behavior usually develops around the age of 10-12 months.
