I dont know what to do...

Ok i havent posted in 3 weeks... my sweet baby girl is 4 weeks 3days and i love her more then anything but i started back to work and ive come to dread night time bc ik i wont get to sleep. Ik it sounds stuip but my hubby has to b up early (i dont go in till afternoon) and so i get up with our baby and he helps on days off and when her goes in later but i still end up being up bc i feel like a awful mother if i sleep....... idk if its just not sleeping that makes me feel this way or wat! I will always make sure my baby is taken care and wouldnt trade it for nothing and i havent talked to anyone about it bc i dont want to sound selfish if its just lack of sleep......

Plz no rude comments, ik it sounds bad.....
