update:
the remaining little 3 oz girl is hanging on so far. hubby has been feeding through out the night. her suction is still very weak. we are holding mom down so she can get some of moms milk in her. she will suck a little on mom then poop out on us, her suction is very week. she still gets a little milk coming out of her noise. we are keeping her in her own heated nursery with a tiny stuff animal that she cuddles with and have the receiver monitor in with her so she can hear the sounds of her sister and mother. (she responds to the sounds of her sister).
I'm still trying to figure out what went wrong. the only thing I could thing of is the docking could of put to much stress on them being so tiny. should I have waited a day or 2 more? I had asked the vet but she assured me it would be fine. (she's 4 days old today) I should of went with my gut feeling.
