The first year of a baby's life is full of many firsts, from walking to waving bye-bye and having their first taste of finger food. As your newborn develops into a toddler, many cherished memories will be made.

Parents can feel overwhelmed by these exciting moments, as they worry that their child is not reaching each baby milestone early enough.

How do you know when babies should achieve each milestone?

Our guide will tell you everything you need to know about all the important baby milestones you will experience with your baby. We'll take you week by week from the end of pregnancy through the first year of your baby's life, so you can look forward to enjoying each precious new memory.

What is a baby milestone?

During your baby's first year, they will be developing rapidly and changing daily. You will see them learn essential communication skills, discover hand-eye coordination, and even take their first steps. These developmental achievements are known as baby milestones.

Even though all children develop at their own pace, most babies will reach certain developmental milestones around a similar age. This provides health care professionals with useful information about how your infant is developing.

These baby milestones can be divided into four categories:

  • Social - How well your baby interacts with other adults and children.
  • Communication - How your baby expresses their needs
  • Cognitive - Your baby's problem-solving skills
  • Physical development - How your baby's mobility develops

This allows each part of your baby's development to be monitored, so any early signs of concern can be quickly detected.

Premature babies cannot be directly compared to full-term babies. Parents of premature babies need to remember to adjust their baby's developmental age to their due date and not their birth date.

Why are developmental milestones important in your baby's first year?

Most baby milestones are just a guide, and parents shouldn't worry if their baby is not reaching all of them at the specified time. This doesn't mean that there are any developmental issues with your baby.

A couple of major developmental milestones, such as talking, can provide an early indication of a developmental delay if a baby is unable to achieve them within a certain timeframe. If a baby is consistently delayed in reaching each milestone, then this can also indicate a development problem.

These children might need extra resources and support, so if families have any worries about their baby's development, they should discuss their questions with a health professional.
