I'm a 27 year old mother of 2 and I have 0 energy. I thought it was due to being inactive but I'm working now (part-time) and I try to get my kids out to play with them but I'm just so freaking tired all of the time. Could this be a vitamin deficiency? Should I try taking supplements? I'm still breastfeeding my youngest and haven't taken prenatals in awhile. I feel badly that I have no energy to play with my kids.
