Say different sounds. Your baby has discovered her feet, and may love to suck on toes. She is getting stronger, and may start to push up on her hands and knees. For safety, remove toys like crib gyms that are strung across the crib. From this age on, your baby will be very interested in toys that she can touch, look at, chew, suck and bang together.
Some parents are able to make a regular date to be with other parents and babies.
Once a week, two or three parents and babies get together for an hour or more. Babies enjoy these play groups. You can watch your babies grow together, and learn from each other. You may be able to use each other for emergency baby-sitting, too. Every parent has days when baby drives him or her crazy.
