Baby milestones: one to six months

Find out what to expect from your baby at each stage during their first six months. Bear in mind that all babies develop differently. If your baby was born early (before 37 weeks of pregnancy) or with a condition linked with developmental delays, such as Down's syndrome, they may reach these milestones a little later than other babies (AAP 2020, NHS 2022a). If you have any concerns about your baby’s development, ask your health visitor for advice (Harvey 2020).
