If you have changed LO's formula due to gassiness or whatever the reason how long did it take for you to see a difference for the better or worse once on the new formula? We just changed LO from similac advance early shield to similac sensitive due to his gas problem (he turns red trying to get his gas out and mylicon doesn't really help) and I was just curious to see about average how long it takes to see a difference. Thanks!
