You and your baby are starting to feel (and act) like separate people. Your baby is starting to sit up, move by rolling, reach out, and act on the world. They worry that you might not come back when you go away and will let you know it. Object permanence is starting to become a thing, where they learn that something that’s gone will eventually come back. Your baby will respond to you giving them lots of things to look at, touch, play with and safely put in their mouth. Time playing on their tummy on the floor will strengthen baby's back and help them learn to crawl.
Babies around this age love nothing more than interacting with the world around them - it’s how they learn, reach milestones and develop their senses. Encourage your baby to smile, babble and grow with these fun toys.
