Sleep & milestone hub
Practical tools for your baby's early years, with space for every baby's own pace.
Plan a sample sleep day
Choose an age and morning wake time. Use this flexible example as a starting point, and adjust around your baby's cues, feeds and individual needs.
Your sample day
This tool shifts a fixed example around your chosen wake time. Nap times and lengths are illustrations, not targets. It does not assess your baby's sleep needs or predict uninterrupted night sleep. Respond to hunger and tiredness cues; follow your clinician's advice for your baby.
Sleep sound guide
Choose a sound to learn more. A sound alone cannot tell whether your baby is well.
Occasional noises can happen during active sleep. New grunting with each breath needs emergency assessment.
Contact a clinician if you are worried, or if feeding, breathing or alertness changes.
Milestones by age
Explore selected skills from the CDC checklists. These are milestones that at least 75% of children reach by each age, not a score or diagnosis.
- Movement: Raises their head while lying on their tummy.
- Communication: Makes non-crying vocal sounds.
- Social: Smiles in response to your voice or smile.
- Learning: Watches you moving nearby.
If your child misses milestones, loses a skill or you have concerns, discuss developmental screening with your child's doctor.

Occasional noises can happen during active sleep. New grunting with each breath needs emergency assessment.
Gasping may mean breathing difficulty. Seek emergency help if it is happening now or your baby is struggling to breathe.
Nasal sounds can occur in newborns. Seek care if feeding or breathing is affected.
Babies may experiment with their voice. A harsh noise with breathing or visible breathing effort needs urgent care.
A whistling breathing sound needs prompt medical assessment. Breathing difficulty needs immediate care.
Digestive and throat sounds can occur. Seek care if the sound accompanies choking, feeding difficulty or breathing trouble.
Breathing much faster than usual can be a warning sign. Seek medical assessment promptly.
Brief whimpers can happen during light sleep. Check your baby's breathing, colour and responsiveness.
An occasional cough can clear the airway. Sudden coughing with choking or breathing difficulty needs urgent care.
Hiccups are common in babies. Discuss persistent episodes that affect feeding or comfort with your clinician.
