Marcia: I KWYM about people telling you that they know better about your baby..It definatley sounds like Hudson has reflux, Felix used to do HUGE projectile vomits once or twice a day and they thought HE had silent reflux..So hudson definately beats him in that department. It is NORMal for babies to vomit mini vomits (the kind that coats their tubes) and then they said the big ones occasionally are normal too..eg when they are overfed or just "off" but vomiting after every feed or even most is REFLUX! I know you don't need to be reassured of this because you are aware of it..but just wanted to add another agreeable voice to your side!
I hated my mother and her friend always telling me "oh he's crying because he needs to be burped..or oh he couldn't be hungry AGAIN, he just wants to burp..they spent all their time with him trying to burp him when all he wanted was to be hanging off my breast! SIGH!

With the rolling thing, some people say that they rollfrom back to stomach first and others stomach to back..I think it depends on the baby..Felix rolled from tummy to back at 4 mths once and then didn't do it for ages again..and he has only once done the back to tummy thing..but now he rolls off his tummy easily..I guess because he preferes his back.. Anyhow as long as they have rolled both ways by 6 mths they are doing fine! (that is the developmental milestone in health books)
