First, I'm sorry to hear that your nephew is having such a rough start.
For the record, I can't stand people who say that babies are lazy. Grrr.
My son lost a lot of weight after he was born, and he wouldn't latch on...and I was bound and determined to have him breastfeed because I had been sucked into the "breast is best"...and I do believe it is, for the most part. I tried everything to get him to nurse and felt like such a failure when he just refused and kept losing weight...talk about a lot of tears!! I finally got a breast pump and gave him my breast milk via the bottle. Has his mother tried that?
My first thought, after getting annoyed at the person who said he was "lazy", was that no matter what, I hope his mother doesn't get caught up in the, what I call "false advertisement from the Le Leche League" that breastfeeding is easy and natural...it's hard and it's not for everyone...and that is OKAY. I kicked my self for five months trying to get my little man to latch on ... to no avail... but he did get breast milk for those five months and then he switched to formula...and he is a healthy 15 month old who weighs in at 30lbs!!!
If she can, ask Mom to contact a Home Health Nurse, I had the most wonderful lady come to my home at no charge for three months to help me...and we've since become friends...check to see if the county she lives in provides this service. Otherwise, check to see if there is a Breastfeeding "Clinic" in her area...it's also free of charge, the ladies here accepted me into their office bawling "like a baby" at my wits end and were so kind and understanding...with no judgment whatsoever. I do believe these two "services" saved me and my husband from going insane. lol
God Bless this mom for being so concerned and wanting to do the right thing by her baby...please just let her know that formula is not the worst thing that can happen to him.
SO, all in all, (and I'm sorry for the lengthy message)see if the hospital has breast pumps to loan out or rent and have her try that just to get some breast milk into the little darling.
I will keep her, you and the baby in my thoughts.
