Moms, if you could name one thing you hate (or has challenged you so much) at each of the trimesters of your pregnancy, what would they be and why?

My wife would always complain of food! She's been too picky on the first trimester, been to demanding of all the food she wants to eat during the second. The last trimester has been really tough for her because she can't eat too much because our baby has really grown big. Nonetheless, I tried to understand her crazy hormones. haha
