Much to do: encourage crawling forward practice using both hands, together and separately, and enjoy peek-a-boo games that help baby understand object permanence. Also, notice how baby is expressing interest in the connection between her actions and their consequences (cause & effect).
Baby now starts crawling, gaining independence as she gains mobility. She may start to sit on her
own to better play with her toys.
Memory enables her to explore
her surroundings, like
understanding how to make an
object move again and again
(cause & effect), and to develop
the differentiates between those
she knows and strangers.
