@Jenniwithanl: Glad you enjoy the motherhood. My DH NOA is certainly caused by a medical condition. It is just very unfortunate that the Dr back then didn't fix the problem sooner. However, i am not sure if my MIL drank large amount of soymilk during pregnancy and thus the problem. He isn't an asian origin so i doubt that would be the case. I actually looked into radiation after chernobyl disaster. BUT this would mean that a world wide problem rather than an isolated incident.
I am not the in mood to enjoy being a motherhood at the moment. Bub is having stomach/painful gas problem. A normally happy baby is very unsettled and upset. I changed the formula. I don't know what else to do. It is so heartache to see him suffering everytime he has an episode of passing gas. It has been more than a week now. We hesitate to bring him to the hospital before the first set of needle.
