food and formula not mixing making my baby sick

Kandi • Mom to 3 beautiful girls. Expecting august 2020

my daughter eats everything we eat but here recently shes eating more regular food. everytime she wants a cup of formula If it's been an hr or less since shes ate our food then she starts throwing up. if she eats the regular food with no formula she doesnt throwup. has anyone else had this problem if so what did you do to help fix it any input is appreciated. has anyone swapped over to whole milk yet do yall think that will help.
