Here are some of the baby development milestones to watch for in babies ages 3 to 6 months.

By the age of 3 months, most babies are beginning to smile and laugh and to make cooing noises when spoken to. Some babies are able to pull themselves up and stand with support. By 5 months, babies discover their hands and feet and enjoy playing with them. At 6 months, most babies are able to roll over in both directions.

Many babies ages 3 to 6 months are able to grasp objects and move them from hand to hand. At six months, many babies recognize the sound of their own name.  Some of the more advanced skills for a 6 month old baby are crawling, sitting up without support and imitating simple sounds. Some babies begin to cut teeth at 6 months.

The range of development skills begins to vary quite a bit from baby to baby after the age of 6 months. Parents should remember not to compare their baby with others too much and to talk to their doctor about any developmental concerns.

When my youngest son was a baby, it took him a long time to complete toilet training. At age 3, he was good about peeing in the toilet but would request a diaper when he needed to poop. After a well-meaning friend suggested that we take him to a psychiatrist, we discussed the problem with our pediatrician. She smiled at us and said, “When he’s a man, do you think he’ll need a diaper to poop?” Her humor defused our worries and within a few weeks the problem worked itself out. As soon as our son started preschool, he stopped requesting diapers. Since then, I try to remember to take the long view when it comes to worries about childhood development.
