What games does your LO like to play that don't include games that you physically buy? We have been introducing games that don't require materials, it's nice because if we need to entertain them for just a few minutes without getting anything out, this does the job! A few we have played so far are:

Hide and seek (huge hit!)
I Spy
Attempted Mother May I but it didn't work too well, think they need to be older

A few I want to try:
Duck Duck Goose
Mr. Fox
Simon Says

I know there are more, I loved these types of games as a kid! Share your ideas
