told her that I was worried cause he was spitting up a lot and crying after too. She said she wasn't worried cause he was gaining well.
(HUGS) I have no idea why but there is this huge misconception that if your LO is gaining weight then their reflux can not be an issue. Babies with silent reflux often gain weight well (mine was a chunky munky!) but they get awful pain from the stomach acid coming up into the throat. Like heartburn) You may find your LO has dairy etc intolerance's, which it sounds like you worked out yourself
He may not have reflux, but it is certainly a possibility. A second opinion would certainly be worth it I think

Here in NZ ranitidine is usually the first med offered to silent refluxers. Try not to worry about weight, really though he isn't that small and certainly not worryingly underweight IMO! In our plunket guide 13pds is average for a 3 month old and these are old charts based on bottle fed babies. However, if he hasnt gained in a month for example this could be why the Dr is worrying.
I would also stop the rice cerial. ....it can be so constipating for babies, even when they are ready for solids, and 3 months is really really young. WHO recommends no earlier than 4 months because babies systems are not mature enough to digest solids.
(HUGS) sounds like you have had a bit of a rough time
