My DS (3 weeks old) is a spitter, and I think it's getting more painful for him just like your LO. Last night he screamed every time he tried to nurse. DS1 did this and was diagnosed with reflux. I'm praying this one doesn't have it too. Have to admit, I havent been strict on my allergy free diet. OH - and there's the overactive let down that chokes him every time he tries to nurse. Wish I could enjoy those wonderful nursing moments other moms talk about. All I get lately is a screaming, puking, hungry-but-can't-eat, baby.
I'm usually a non-medicating mom, but I'm seriously considering Zantac. It's preferrable to formula though. And if it works like you say, Babycakes, it might be an option for us. Any one think it would work if *I* took the Zantac and he got it in my breastmilk?
