I found that my DD was like that either when she had wind OR if i ate something that made the milk taste different for me it was anything spicy or the time i had 2 sips of wine a while after she would scream as well ,same with the food. But she also did this when she was younger when she has bad wind.

Its so upsetting isnt it? I would feel awful when there was nothing really i could do. hang in there hun i hope you work out what it is
