My baby is 4 months old and has been sleeping through the night for almost two months so I get a solid 8-9 hours a night but for some reason I STILL feel exhausted. I know breastfeeding takes a lot out of you but is it normal to still want to go back to bed an hour after being up, or to NEED to take an afternoon nap? My only other thought is that maybe I still need to be supplementing with iron? I do take a multivitamin and eat very healthy but near the end of my pregnancy I needed to supplement my iron.
