Hi trt, I'm sorry I'm only seeing this now but i don't come on here very often anymore, but I thought about you today & thought I'd check in on how things are. I hope things have settled with your grandson now, did you find out what the issue was with your daughters blood? I ask because I'm Rhesus negative & that can cause the problems you mentioned before, it also means if the baby is rhesus positive then it is more likely it will be born with Jaundice, which was the case with both my boys. & they were both born at 38 weeks, With my eldest he also had a calcium deficiency so was in hospital for over a week after he was born, I too was back & forth to hospital for blood tests & he was about 3 months before we got the all clear. He is a fit & healthy 15 year old now & we've had no issues since. My youngest was also born with jaundice but I was able to deal with it much better as I'd been through it before, my midwife at the time suggested I try & see if I could 'flush' it out, so I fed it every 3 hours whether he wanted it or not & within 48 hours all signs of jaundice had gone. Obviously I'm not saying this is what your daughter should do but it shows that they do things differently when its the 2nd or more baby.
