Help

I just hit my son. On his bare thigh. He's two and change. He didn't sleep last night and neither did I. I had three hours of let's pretend I'm have a nightmare. Where he would randomly scream at the top of his lungs so I would come rushing. Then he was either pretend to be asleep or try and babble at me. Then this morning I've had food thrown on he floor. Toys thrown at me, at the wall. He's climbing the baby gate. Wants biscuits and slices of bread. I'm trying to manitain boundaries and I've said no and given him timeouts. It wasn't even 12noon and we've already had six. He threw his lunch on the floor. So I pick him up and took him to the bathroom to clean him up and change his nappy. And he kicked me in the stomach. ( not a good week to do that) and I hit him. On this thigh. I left a marked. A red and white hand print. I didn't mean to hit him so hard. Just a tap to get him to stop. As soon as I had done I felt awful. He cried in pain. I finished changing his nappy. Give him a massive hug. Told him I was sorry. I did alll the things I've been teaching him to do when he hurts someone. He clung on to me. Crying. In the end I put him down for his nap. He's asleep now. I phone my SO and told him what i had done. He was understanding and forgiving. I felt like a POS. it isn't he first time I've smacked him. But it's always been a tap on the hand or or he bum. How do I stop? I don't want him to look back and remember me smacking him. how do I not react? I'm looking for any advice. I know what I did was wrong. What can I do? via /r/Parenting http://ift.tt/2vIQo1L
