About now, your baby's laugh is likely to be the most welcome sound in your home. She's truly learning to communicate with you and others around her. She can grasp a rattle. Baby laughs out loud. She squeals with delight.
Baby smiles spontaneously.
She pays attention to very small objects. Baby experiments by making new sounds. She recognizes parents and siblings. All babies have their own internal developmental timetable. If you have concerns about your baby's development, discuss them with her doctor.
