I don't know why your baby is vomiting, but i do suggest you take her to the vet, i just spent this past weekend worrrying about my furbaby, because she was vomiting, i took her to the vet and she had to be put on IV
the vet said that they can become easily dehydrated and then that could lead to becoming hypoglasimec, and then that leads to sezures. i'm sure you dont want this to hppen, but the best bet take her in for a check up.
Hope she feels better.
