Each child is unique. While some behavior and growth milestones tend to happen at certain ages, a wide range for each age is normal. It is okay if your child reaches some milestones earlier and others later than the average. If you have any concerns about your child’s development, check with your healthcare provider. Here’s what you might see your baby doing between the ages of 2 and 4 months.
