I am experiencing the same problem in my 6 week old. I sure hope this is something they overcome, as I hope to keep bf'ing my son, but hate to see him so miserable!
Back in April, I had a 12.6 pounder, and right at birth, they had to give him sugar water cause his sugar was 23. And yes, that messed everything up. I'm still trying to recover from the supplementing, and he's 6 weeks as of yesterday....
I just had my second child, William, on April 2. Get this, :
he was 3 weeks early, and 12lbs 6oz. What a boy! I'm looking forward to following this board!
I thought that I was the only mom that "tried" to bf when I had my first, although it didn't work out with him. I'm half and half with this son, trying to get to full time bf'ing.
