question: Hello I have a 15 and a half month baby girl. We are slowly taking away her bottle and she only drinks one at night and one in the morning. After her last bottle last night she got very fussy and started crying, my husband picked her up and she threw up very white and chunky. Now this morning she did it again. She has no known food allergies or a fever or nothing else and she only seem to do it after she drank milk. What could this be???
