I tried giving my boy a couple ounces of formula last night to see if it would hold him longer through out the night. Las time he had formula was in the hospital and we only supplemented with 15mls after every feeding for 4days. This whole time he has been EBF at 19 weeks. So he tasted the formula and he literally gagged And threw up. I guess we can say he only wants mommy’s milk and I’m 100% ok with that. He hated Formula. Has this happened to any of you?
