Hello K.. I had a similar situation when my daughter was young. She was eating so much, throughout the day, that it seemed like she never got full. My mother in law starting adding rice cereal to her bottles, which infuriated me, because my daughter was still very young (I don't remember the exact age because it was 17 years ago!), probably around 2 months or maybe even a couple of weeks. While it never seemed to hurt her, and it truly did help with her appetite, I'm not sure that I'd recommend it, only because I think it upsets their tummies (although we didn't experience that). Also, while I was pregnant with her, my ob/gyn said I had a tapeworm, and that it would pass when I had my baby. I always wondered if it ever did, because to this day, her appetite is still insatiable, and she's not the skin and bones she used to be. I would say, off the record, to do it, but add it slowly, which I know contradicts what I said before, but I just really wouldn't want to give you any bad avice. I also think (sometimes) that doctor knows best, and stick with his/her directives. It's a tough call, and I really feel for you. Good luck to you :)
