When bedtime is resisted, respond with the same predictable flow each day.

FAQ

My 18 months baby is different from these guidelines — is that okay?

These numbers are just average references, and the normal range is much wider. Babies vary a lot, so look at the steady trend rather than a single point in time. If you're worried, talk with a professional.

The information on this page is general reference material based on widely used parenting standards (such as the WHO Child Growth Standards) and does not replace medical diagnosis or treatment. Babies vary greatly in how they grow and develop, so if anything concerns you, please consult a pediatric professional.

Your baby's guideline is made by your baby

Averages are just a reference; your real guideline is your own baby's records. With aldagado, just speak a few words and feeding, sleep, and growth build into your baby's very own patterns.
