My formula fed baby seems to be constipated and struggles a lot with pooping and I dont know what to do. For reference:

1. My baby is 11 weeks old

2. Started by breastfed but then had to switch to formula

3. We settled on Earths Best Organic formula, the red can and have been using it consistently for 2 weeks

4. We use Gerber Soothe probiotics for 3 weeks

What should I do?? I really hope it's not the formula causing this because I really wouldnt like emfamil and similac as options to feed my baby 😞
