Hi i am looking for some help/advice about what i can do to get my 12 month old to start eating again. :( When she first started eating solids she was hard to feed but got better but for the past few days all she seems to be doing with any food we offer her is spit it back at us. We have tried letting her feed herslef but she wont do that either. We have tried different foods with still no luck. Any help/advice would be great. Thanks in advance. TaniaC
