I understand that they can't communicate clearly just yet and this is his way of communicating with me, but it's almost always the worst when it is bedtime and there isn't anything at all wrong with him. He has already had plenty of mommy time (gets mommy time all throughout the day as I'm a stay at home mommy), he's just been fed dinner a few hours before and goes to bed right after getting a Pediasure bottle (due to them being small from being premature their pediatrician has them on Pediasure to get their growth caught up), he isn't teething right now (he's going through a rest period of not teething right now), he isn't sick, he isn't bored, and I don't believe in letting them go to sleep with the television on because it's bad for their eyes to watch tv in the dark room. I believe in having them on a set bedtime routine and schedule and want them to maintain this schedule. But, Jayden doesn't want to maintain this schedule and this is when these tantrums come about the most.
At other times, the tantrums come when he starts to get rough when playing and I stop him and tell him no. Then he will throw himself down and start to scream/yell and just hit me some more if he is within reach. I try to stay out of reach of him when he wants to hit and just reinforce the "no", but it seems this isn't working. He was in the NICU the longest and I wasn't able to be in the NICU with him all of the time he was in there, so I'm wondering if he could possibly have some separation anxiety when he's throwing these tantrums when I go to leave the room? Other times I think it's just because he is angry that he isn't getting his way.
