Switch from Prilosec to Prevacid

ANy idea if switching from Prilosec to Prevacid would take time to again to notice improvement?

I switched as I read that Prevacid was more effective & I figured it would be easier to keep the meds in my babes. However, they have been back to being much fussier while eating & Im regretting my decision.

They also seem to be hurling more, I didnt think either med helped spitting up/hurling but they seemed to do much less on Prilosec.
