Today we played with buttons, I would not recommend this if your child is still mouthing. I really didn't have any set plan with this activity I just know that this would be great for exploring and fine motor. Adeline seemed to enjoy it, she is always interested when I give her something new to work with. We played with the buttons for awhile and then I put some in a sock wanting her to try and reach inside to pull some out. This was hard, and she soon figures out how to just dump the sock. Ok, next time I need a tighter sock.
