I feel selfish.

Chyna
My mom came to live with me during my pregnancy due to an abusive relationship. I've had my baby about a month ago and she's been such a big help. So much so that I feel like I'm not being a good mom. My mom changes most of her diapers. She has stay with my daughter out in the living room my mom on the couch and my daughter in her bassinet just so I can get some sleep. (My daughter started feeding too much my breastmilk couldn't keep up had to put her on both so she's bottle fed) and on top of that when I stay up late cuz my girl won't fall asleep and stop fussing till about 1-2 in the morning let's me wake her up at 5-6 in the morning to do her next feed while I go back to sleep and she let's me sleep till I wake up whatever time that turns out to be. I just feel like I'm selfish for choosing sleep over my daughter. I feel selfish for letting my mom do these things. I feel like a bad mom. Like I'm not there for my daughter. I've talked with my husband and mom about my feelings and they say I have nothing to feel guilty for I had a c section and I'm still recovery that I need as much sleep as possible. It doesn't stop these feelings for long tho. Any advice?
