Allergic reaction???

I was at my in laws yesterday to get a break I have a 5 month old baby and she just started eating pureed foods(doctor said it was fine) but Sophia's(my baby) great grandma gave her bananas and pudding without telling me and she was trying to give her gravy too but then I told her no because I gave her a new food the day before and I need to wait a couple days to give her anything else and theres milk in that she cant have milk.....I'm so mad she gave her all these things without talking to me about it and I cant trust her around my baby alone anymore. But later that night when I got back home Sophia was having such a hard time falling asleep she was crying uncontrollably and it was a miserable night....so much for a break right. But she doesn't have a fever, no hives or anything like that but it's the next day and shes still having a hard time falling asleep and it's like shes just uncomfortable I'm currently cuddle with her and shes finally asleep but I'm not sure what to do...

Thanks for the comments everyone I really appreciate it💖
