I had this same issue with R when i first started him on solids so like you i stopped them and tried again a few weeks later and things have been fine this time around.

I don't agree at all that bubs needs to get used to having an upset tummy, i mean if something was giving us an upset tummy we are hardly going to keep eating it are we - so why would you keep feeding it to a baby! It's quiet obvious that the solids are causing Missy pain and the reflux flares back up again....your doing the right thing darl in just going back to BF she will be ready for solids in her own time - don't worry what anyone else has to say, she is your baby.

Take care x
