It’s crazy to think that some babies start saying their first words and sounds related to words around 6 months of age. Babies can begin those clear words (“mama”, “dada”, etc.) around 9 months of age and the repertoire can continue to flourish from 12-18 months of age. We do find that sometimes these word explosions can affect baby’s sleep negatively if they don’t have healthy, established rhythms already. Baby can wake up in the middle of the night or during a nap chatting away and practicing his or her new words! If baby is happy and not crying, we would recommend allowing baby to practice their words and then put themselves back to sleep on their own (if happy). We usually see things go pretty well after a few nights of practicing the new language skills!
