Issues with formula?

Jasmin

Hi for those moms who are feeding with formula, has anyone’s baby’s had any tummy issues with byhearts formula? My baby is 7 weeks old and I switched her formula from similar 360 to byhearts. She’s been fully on this formula for 4 days now but is still having tummy issues. She’s seems to still be straining and it won’t let her sleep. I’d this normal? Or should I change to a different formula?

Thank you
