Spitting up

Be

My lo will be 8 months old this month. After a bottle she is still spitting up bad when we go anywhere we take atleast 2 change of clothes 8-10 bibs and 5 burp clothes. I also take me a change of clothes. I have switched formulas but nothing is helping she is also on acid reflux medicine. We have also done soy, Thinking of trying the liquid formula. Anyone have suggestions or have had better luck on the liquid?
