Oh, I'm glad Jacob is here and being cared for, but I'm so sorry he's not well right now. Sending lots of recovery vibes. I hope his heart problems are resolved quickly, and that he can start nursing soon. Lots of hugs to Irishcupcake and her dh, this must be so hard for them.
My son was born 4 weeks early and very jaundiced. He wasn't waking up for feedings and the hospital told me not to wake him up!!! I followed their advice and it ruined our bf relationship. I think contacting LLL is a great idea. Also using cold wash cloths on their faces half way thru feedings (ds would fall asleep after about 4 min) and stripping him naked helped too. If she can get a good pump and pump every two hours that would have saved us (Like the medical grade ones). Also I was told later a nipple shield would have really helped too, if like DS, he's just too weak to suck.
She's getting help early so I'm sure they'll be able to resolve this, but I know how scary it can be!
