My ds hated being a baby is how we've always described it. He was irritable and frustrated not being able to do things (that were skills he didn't have yet). This mostly resolves around 1. Ds is 5 now and does have occasional crying/ yelling episodes, but I think it's related to tiredness, hunger, and thus decreased self- control. He has intense feelings which I think contributes as well. Good luck and stay consistent.
