Separation can feel different now

Object permanence is changing how distance feels

The Millie's Team By The Millie's Team · Parenting Notes

Around week forty-three, separations may feel bigger to your baby. Knowing that you still exist when you are out of sight is a new and complicated idea.

What is happening

Object permanence is developing. Your baby now understands that you are still somewhere, even when they cannot see you. That can be reassuring once it is fully formed, but during the in-between stage it can feel unsettling.

Is this normal

Yes. A short period of stronger separation feelings around this age is very common. It is a sign of healthy attachment and growing understanding, not a step backwards.

What to expect next

Over the coming weeks, your baby will keep building trust that you always come back. Separation feelings usually ease as that trust deepens, even when the world keeps getting bigger.
