Trish, she sounds exactky like Zyon...
He rarely seemed hungry as such, he only opened his mouth a tiny bit & just really didnt seem interested... His attachment was never fantastic in the first 2 months, but I only got small grazes, nothing too bad!
I would get so worked up & stressed trying to get breast in his mouth, he'd just not really suck... I was so scared I was failing... At about 9wks things seemed to change he finally started to search out my nipple at feed times & would latch on like a vaccum....
I also had him checked for tongue tie, but they said not really(?)

Anyways he feeds perfectly now & bloody often too lately!

I hope everything goes well at your appt.....

My friend just had her baby #3 & is cup feeding her as she simply will not suck the nipple in!!!!!!!
