When Can I give my daughter jar food. She will be three months in the 21st I gave her some peas last night and she seemed to enjoy it this morning prunes. I just don’t feel like her formula is fulling enough for her and she projectile vomit almost after each bottle feeding and her doctor says to put cereal in her bottle but that doesn’t work.she is on Gerber good start gentle.I am only introducing one jar food at a time and it is the stage one so it’s still really watery. She seemed to have slept better also
