Anti reflux formula

Anyone’s babies on anti reflux formula? My 2 month old is on cow and gate anti reflux and regurgitation milk but she’s struggling to get it out of the bottle due to it being thicker. Should I move her to a medium flow teet? I know it’s 3 months plus but I’m not sure what else to do?
