Baby Milestones: What to Expect in the First Year

The first year of a baby’s life is an incredible journey filled with rapid growth, delightful discoveries, and heartwarming ‘firsts’. From a baby’s first smile to taking those tentative first steps, each milestone marks a unique step in your child’s development. As a new parent, understanding what to expect during this formative time not only helps you track progress but also gives you the confidence to nurture your baby through every stage.
