My 4 yr old has been so good and matured quite a bit since his 2 yr old brother has started the terrible twos. But I am pregnant. So I feel you. I am getting zero sleep these days.
I am right there with you - my older DD will be 4 in June and my LO turned 2 in March. I can't decide who has the better tantrum - the 2 year olds certainly last longer than anything my older DD every did but she has them less often so I think its a coin toss at this point. At least the tantrums with my almost 4 year old are way less. I love her becoming more independant for the most part.
