My 4 yo almost 5yo is so unaware of her baby brother it scares me half to death. Last night he was chillin in his rock and play and she was messing around and fell into the back leg of it. If my foot would have not been on the rock and play little man would have been seriously hurt. Any advice on how I can make her pay better attention when he is around? I have talked with her numerous times but it seems like it always goes in one ear and right out the other.
