Baby care from 4 to 6 months
This collection helps you find information about sleep changes, new skills and preparing for solids. The age band organises the reading; it does not tell you when your child must reach a skill, change naps or start a new food.
Choose one question before comparing charts
For a sleep question, compare waking or asleep times using the same definition and include known gaps. For a development question, record what you saw and the circumstances. For starting solids, use the linked readiness guidance and individual advice rather than treating this page’s age label as permission.

When and how to start solids, the signs your baby is ready, what to offer first, how much food by age, and how advice differs in Australia, the UK and the US.
Iron-rich first foods for babies: what to offer and why
Why babies need iron from around 6 months, the best iron-rich first foods and how to prepare them, what helps absorption, and when iron drops come in.

Put it into practice
Try a worked recording example or use the free printable feeding and sleep log. Neither needs an account. The guide library links to its health sources and states the guidance region.

Age is a way to organise reading, not a timetable for feeding, sleep or development. These collections have not been independently clinically reviewed. Use your child’s individual care plan and read our editorial standards.
