Exhaustion!

Tracey
Had my baby one week ago via csection. She has a slight case of jaundice due to our blood types not matching so they told me I had to feed her as frequently as possible to flush out the bilirubin. I'm exclusively breastfeeding so it has been very hard on me. I'm so exhausted to the point where I just cry to my husband. He try's to help he stays up with me through the feedings and cooks for me and brings me food in bed. I'm just so tired and I don't want help from any family I feel my baby is so tiny and new and just needs her mommy right now. It's just this week has been so tough recovering from surgery and caring for my newborn and 3 year old all at once ?? I wish I didn't need sleep.. Any words of encouragement would be much appreciated.
