What do you mamas do to entertain, play, teach your babies at this age? 
I don't recall what I did with my son 5 years ago. 🤔 
I hold toys out for her to look at, tummy time, mostly she jus enjoys laying flat on her back and kick up a storm. She will also push/ stand up when holding her up. 
I was curious about the keyboard gym toy that babies can kick? Good idea? Yay or nay.
