Understanding Infant Development

Every baby develops at their own pace, but developmental milestones provide useful benchmarks for tracking growth.

3-4 Months

Holds head steady, reaches for toys, follows objects with eyes, babbles, smiles at people.

5-6 Months

Rolls over, sits with support, begins to eat solid foods, recognizes familiar faces, explores objects with mouth.

7-9 Months

Sits without support, crawls, pulls to stand, understands "no," says "mama" or "dada," develops separation anxiety.

10-12 Months

May take first steps, uses pincer grasp, waves goodbye, follows simple instructions, has favorite toys and people.

When to Talk to Your Pediatrician

Every child is unique, but talk to your doctor if your baby isn't meeting milestones or if you notice regression in skills already gained.
