I have an almost 2 year old and a 7 week old. My toddler is being very naughty lately she has learned what no meant before her sis was born but now she seems to be rebelling. Everything is no no no. My biggest problems is trying to teach her she can't be picking up her sister or being ruff on the bed. IT is so bad that I have to put the baby in her bed to use bathroom cook etc when home alone because I just can't trust her. Also getting her to understand that it isn't a game and not funny when she gets in the street. I am at my wits end I know some of it is terrible two's but I need a good method for correcting her that may actually work. Also my baby cries a LOT I don't think its colic because she has been like this since birth. Could it be bad gas or just her nature?? She is fine if I am holding her she doesn't sit or lay even five minutes quietly not in her swing/bouncy seat, boppy, or playmat. is it Normal?
