Pooping a lot!

My baby is about to turn 1 in a few days. She’s been completely weaned off of breastmilk for almost a full 2 weeks now and has been on pea milk. She is still eating the same foods she‘s been eating but these past few days, shes been pooping 4 times a day! It will be like half and half with some being solid and some mushy. Maybe too much milk? She did sport a rash a few days ago that I discovered is probably from eating Gerber lil meals. So maybe the increase is from trying to try that food out? Thoughts please.
