When is object permanence

You can tell that your baby is starting to understand object permanence if she starts looking around for a toy you've just hidden. Separation anxiety usually starts around this time, too. In a way, separation anxiety is related to your baby not full understanding object permanence.

At around 10 months old, your baby will most likely have a full understanding of the concept of object permanence. And if you hide the toy and then remove it from its hiding place and hide it someplace else, he will assume it still exists and will keep looking for it. Or hide a toy and encourage the child to find it. Always show the child the object first, talk through what you are going to do and perhaps encourage the child to start hunting by looking for the toy under some cushions.

Provide containers with small objects in them. Object permanence often coincides with separation anxiety. However, that often changes at about eight months old. At this age, a child not only grasps object permanence but also has developed a strong attachment to the significant adults in their lives.
