Question

How Old Should a Baby Be to Sleep Through the Night?

Answer

According to professional opinions, generally speaking, babies are more likely to achieve overnight sleep around 18 months old. However, this can vary depending on individual differences. For breastfed babies, they may take longer to start sleeping through the night, usually after they have given up the nighttime feeding habit. Moreover, if the baby doesn’t use diapers, they may not be able to sleep through the night until around 3 to 4 years old, as nighttime urination needs may affect sleep.
