Hi, my baby is 8 months and 2 weeks old. Monday she had creme fromais for the first time, which I believe is made with cow's milk. The following day she had diarrhoe 2/3 times early in the morning. However the rest of the day went well although she seems to develop a recurrent cold. Today I tried to give her her usual milk at 6 am and she vomited after the first mouthfull. I left it there & tried again at 8 am. She had less than other days but after a few minutes she vomited until the very last drop of milk she had. Is it got to do with the introduction of cow's milk? Cold? Or the pasta (carbohydrates) she had yeasterday? Or else?
