My 21 month year old is jealous of my 3 month old and she keeps trying to hit him with toys! Today she hit him on the head with his key toy😤He seems okay I mean he didn’t really cry or anything but idk what to do about that. I gave her a tow tow and put her in time out so maybe next time hopefully she won’t do that. I make sure to watch her around him at all times but sometimes she’s too quick for me!
