Nutrition-wise, ice is okay since it's just water. I've heard that chewing on it is not good for your teeth, though.
I was told to chew/ suck on some ice if im feeling nauseas its suppose to help calm ur stomach so i dont thinks its bad. Plus i was also told to drink cold stuff if i ever wanted to feel the baby move so i doubt it will be harmful
Its water... So nothing bad about it at all.
Why would ice be bad for you?
It can be damaging to your teeth, even if it is the soft or chewy ice. Keep that in mind, I just wouldn't do it too incredibly often.
