At four months, most will smile and coo, most will press down with their feet if you stand them up. About half will start rolling one way and holding onto toys. A few may be able to start imitating some simple sounds you make.
When you use a development chart like this, keep in mind that all babies are different. Some will be driven to master physical skills first. Others will concentrate on mental skills and lag behing on the physical ones. Some babies may seem to surge ahead while other lag behind on everything. "Gifted" is meaningless until a child hits grade school and most differences in kids even out long before then. If your child falls behind her age mates by a couple months, talk to your doctor. Otherwise, do NOT compare and do NOT brag. It's not healthy for either of you and it's no nice.
