I get what you are saying. I EP out of necessity. My fourth baby -- after having successfully BF three other children for 2 years each -- cannot nurse because he has a cleft palate. He cannot nurse effectively enough to do well by breastfeeding only. So I pump.
And it is AWFUL. You do feel like all you do is pump and feed, pump and feed. Because you do. 120 minutes a day in pumping alone. Washing up. Feeding, which takes both hands. I added up how many hours a week I spend with all of this, and it's 46 hours a week. That's probably significantly elevated because my baby can't eat quickly, even with a special needs feeder.
But I keep doing it because it's what is keeping him healthy. The cleft team tells me that. The ped tells me that. And it's amazing.
My suggestion...work HARD at getting him to the breast. Because, in the end, that will SAVE YOU TIME and give you more time for that bonding experience. Bottle feeding formula won't save you any time.
It only works for a working mom when she can BF (and BFing is so much easier than what you've been having to do) OR if she has someone who helps her with the baby at night. I can't do anythign all day, but when DH is home, he helps me with the baby while I try to catch up with stuff at night.
I will say this...it does come. And it's not always like a lightning bolt. It's only been in the last couple of weeks, when I could spread my pumping out a bit, where I felt like I could suddenly breathe a bit. My house is destroyed, I don't have much of a life, my kids are all neglected (not really), but I feel finally like I can spend a bit of time with my baby and get to know him.
