One day your baby is happily going to anyone, and the next they are clinging to you like velcro and melting down the moment you step out of sight. If this sounds familiar, welcome to separation anxiety. It can be exhausting, but it is also a completely normal and actually healthy part of your baby's development.

What Is Separation Anxiety?

Separation anxiety is the distress a baby feels when separated from their primary caregiver, usually a parent. It shows up as crying, clinging, fussiness, or even full meltdowns when you leave the room, drop them off at daycare, or hand them to someone else.

While it can be hard on everyone involved, separation anxiety is a sign that your baby has formed a strong, healthy attachment to you. It means they know you, they love you, and they want you nearby.

When Does It Start?

Separation anxiety typically begins around 6 to 8 months of age, though some babies show signs as early as 4 to 5 months. It often peaks between 10 and 18 months, when it can be at its most intense.

After the peak, separation anxiety usually starts to ease gradually. Most children show significant improvement by age 2 to 3, though it can resurface during times of stress, illness, or big changes like starting a new childcare situation.

It is also common for separation anxiety to come and go in waves. Your baby might have a rough week, then seem fine for a month, then have another clingy phase. This pattern is normal.

Why Does Separation Anxiety Happen?

Separation anxiety is tied to a cognitive milestone called object permanence. This is when your baby begins to understand that things (and people) still exist even when they cannot see them. Before this stage, when you left the room, you essentially did not exist in your baby's mind. Now they know you are somewhere out there, and they want you back.

The problem is that while they understand you still exist, they do not yet understand that you will always come back. That takes time and repeated experience to learn.
