My baby got his shots 3 days ago and since then has been having fits of screaming like someone is killing him and he won't sleep longer than 30 minutes -1 hour and just cries and cries. I don't know if it's from the shots or a sleep regression. I've been giving him tylenol and baths but it isn't helping much. I'm so tired and sick of this and honestly I just can't fucking stand him right now. I know that sounds bad but it's true
