Here's what you might see your baby doing between the ages of 2 and 4 months.
Each child is unique. Some behaviors and physical milestones tend to happen at certain ages, but a wide range of growth and behavior for each age is normal. It is natural for a child to reach some milestones earlier and other milestones later than the general trend.
If you have any concerns about your child's own pattern of development, check with your healthcare provider.
