Constipation remedies for baby

Samantha • Married to my best friend 08.09.14. Evelyn Aline 03.22.16 and Claire Elise 10.10.18

So my daughter will be three months on the 22. We changed her formula again last week to Gerber Soy instead of Geber Gentle and has been doing better with tummy issues. Now we are having a bit of trouble with constipation. She has these soft round ball type poops but poops everyday.

I will be calling my pediatrician tomorrow, but is anyone else having this problem? Any remedies?
