Help-Baptism tomorrow and baby screaming all day

My daughter’s baptism is tomorrow. She use to scream all day due to
acid reflux but has gotten much better. She is always a little gassy
and spits up not a huge amount. Now today she is having such a bad day.
Screaming all day…bad gas…and spitting up like crazy. I feed her
powdered Good Start. Someone once mentioned that the ready to feed is
easier on their tummies. Something about not having as many bubbles and
missing some corn ingredient. I can’t afford to give it to her all the
time. But was wondering if it might make her tummy feel better.
Especially for her special day tomorrow. But I also don’t want to make
things worse. Any thoughts?
