Constipation

Hi ladies!

My 2 year old struggles with constipation quite a bit. Sometimes her poops are totally normal, but then skips a day in going to the bathroom and the next day it’s super hard and it hurts her. Do any of you know of anything I can give her to help her go more regularly and maybe soften her stool a little bit without giving her diarrhea? She’s not a great eater at all, so increasing fiber is not an option because she just won’t eat 🤦🏼‍♀️. Not sure if I should incorporate a probiotic or some sort of daily juice? Thank you!!
