I feel your pain. Hang in there! I did laugh about your husband putting a hex on the house when he leaves. I think they all do that.
My son turned 3 at the end of July. 2 was a dream, not one sign of the terrible 2s. The day after his birthday the terrible 3s kicked in with a vengence. He is just so active and mischievious that he wears me out at the end of every single day! I went to a girls' weekend and I couldn't wait for him to spring some of his devilishness on his Dad. It is really going to give Daddy a taste of what I go through every single day. This was going to be good, I thought.
Oh no! He was a perfect angel for his Dad. I came home and my husband asks, "What's the big deal? He was great and so much fun to be around. I wish I could be home with him every day. You're very lucky!" So yeah. Somehow, the men, they always get the easy road.
Tomorrow will be a better day. I hope your kidlet feels better soon.
