LO started winter squash a couple days ago. Both days (well the days after both times) she's had REALLY runny/watery messy diapers. Is this just normal as she adjusts to some foods? Or does this mean she's allergic or can't handle it, etc? She loves the squash, so I don't know if I should keep feeding it to her or stop. Most foods she's tried she's been fine with. She got this same way with avocado, though, so we stopped giving her that. That was her 2nd food, though, so I thought she was just too young, maybe. She was about 6.5 months then. She's 9 months now and has tolerated other things well. I really just don't understand how to tell if she's having an allergic reaction.
