Your baby will giggle and coo when you play this variation on "peek-a-boo."
Hello and goodbye are part of baby’s first vocabulary. Pretend to hide behind a blanket or chair as you say, “Goodbye.” Then pop out, say, “Hello!” and give baby a cuddle. Repeat, allowing baby to hide.
Saying the hellos and goodbyes each time reinforces the meaning of these words for your baby.
