He smiles, even for a split second
You know those people who say that your baby's early smiles are just gas or an involuntary reflex? Don't listen to them. Recent research indicates that an infant's grin may mean a lot more. The goofy newborn smiles may be your baby reflecting your own smile. He's instinctively building a bond with you.
The first true social smiles start brightening moms' days between 6 and 8 weeks. Your baby may smile when he sees your face -- or Dad's or a big sib's. He's starting to associate your face with feeling good. The bond deepens!
