How do you handle when LO doesn't listen to your "no"?
L is 8 months old and he is getting into everything. Usually he's very good about staying in his play area when I am getting something in the house done but when he grabs things he shouldn't (picture frames, phone charger cord, etc) and I say "no" he just smiles at me.

Is he too young to understand that when I say no, it means stop the behavior? How do you handle if?
