Back at 4months my lo was showing lots of interest in food so I got the go ahead from dr to start solids. It went great for just under 2weeks with just rice cereal and then I tried introducing carrot baby food (just a tiny amount) and he threw up a bunch of times during the night. Went back to just rice for a few days and then tried peaches to same effect. Then when I tried to give just the rice he gagged/turned away so I didn't push it and every time since then he hasn't wanted to eat. I only offer the rice every few days now. He is ebf, but will be 6months next week and I'm kind of stressing about it. Help?
