Your baby’s timeline
Enter your baby’s birth date to see what to expect now and over the coming months, and when specialist input might help. You can also add the first 18 months to your own calendar as dated reminders.
Important information
This timeline provides general developmental information only and is not medical advice. Every baby develops at their own pace.
In Australia, your GP and Maternal & Child Health Nurse provide routine developmental checks. Paediatricians provide specialist care when additional support is needed.
Personalise your timeline
Enter your baby's details to see the milestones for their age, and to add them to your calendar as reminders.
Optional: name and birth weight
Everything you enter here (birth date, name, sex and birth weight) is stored locally on your device only and is not transmitted to any servers. 'Change details / start over' clears it.
Change of details, or starting over?
Calendar apps can’t undo an import. That’s why the download steps start with creating a separate calendar for your baby: deleting that calendar removes the whole series at once.
- Google Calendar: Settings → select your baby’s calendar → Remove calendar → Delete. Every event goes at once.
- Apple Calendar: press and hold (or right-click) the baby’s calendar → Delete Calendar.
- Outlook: right-click the calendar folder you imported into → Delete.
Then use Change details / start over in the tool above, re-enter, and import the new file after deleting the old calendar, so corrected dates don’t mix with the old ones. If the events ended up in your main calendar instead, search your baby’s name there and delete the matches.
Twins? Do one baby at a time: enter their details, download, then start over for the next. Each baby gets their own named calendar.
Milestone ranges follow Raising Children Network and RCH developmental guidance, and line up with the green book’s development stages on the Service Victoria Parent Portal; babies vary, and corrected age applies for babies born early. Typical-weight figures come from the WHO Child Growth Standards (2006). General information only. If you're concerned about your baby's development, talk to your MCH nurse, GP or paediatrician.
