P.S.
I think anyone would be exhausted in your shoes. This is most likely due to your life at this time, and it will improve as sleep routines improve. A couple things come to mind...1) It takes your body and good six weeks to recover from a c-section and a year to recover from pregnancies - remember to get as much rest as possible and eat healthy, as well as drink lots of water. The water will actually do you more good than all the coffee. 2) Have your thyroid checked, a lot of women experience thyroid changes after pregnancy. 3) do you have a friend or family member who can stay over night with you, either for a few nights or once or twice a week, and get up with your older children during the night? Don't be afraid to ask for help..It takes a village to raise a family. 4) Can or does your husband take over night time duties on his nights off? Even if it's only one night a week, it will help you. Oh, and if you have someone to who will get up with your kids during the night...wear earplugs and resist the urge to help :)
