The ped recently suggested starting solids for my 4.5 month old DD to help with her reflux and gain weight, as she's not eating enough formula. So far, I've given her 2 feeds of rice cereal which she's really enjoyed having (to the point where she's grabbed the spoon and my hand to put it in her mouth.)

First time around, she got a little cranky an hour later. Cried for about 15 minutes before she fell asleep. This morning I tried again, and about an hour later, she got super fussy again. She cried for pretty much 2 hours, and wouldn't take a nap. She threw up all over herself and me. A few hours later, she had very loose diarrhea like poop. She's only had one so far, so I can't say she has the runs, but is it normal to have runny poop after rice cereal? Here I was actually worried she'd be constipated.

I'm going to hold off on the cereal for a week and see if her fussiness decreases. I'm not sure what's going on. The ped also said to start veggies and fruit, but now I'm kinda worried. Maybe she's not ready yet?

Any ideas? Also, what kind of a feeding schedule should I have for her? She's on a 3-hour formula feeding schedule during the day, and usually sleeps through the night. She's also on Losec 1.25ml twice a day.
