Hey! I think my baby has sour crop, i do need advice! Ive tried things but they arent working, touching her she doesnt move, shes about 4 months, very quite, stands alone, its horrible. her crop is also dough like and squishy. Should i take her to the vet? she is also pretty tiny, and is in with some 3 month olds and is smaller. She just stands there, doing nothing.
