OP, I wouldn't do anything you aren't sure about until you talk to a pediatrician about it first. Don't think that just because a bunch of people say it's horrible that it is, or that it's okay that it is. Don't let family/friends pressure you into doing things with your baby that you are unsure about.
Talk to your baby's pediatrician once she is born and YOU feel that she may be ready.
Thank you everyone! The last link helped answer a lot of my questions. Now, I think my problem will be getting my MIL not to feed rice cereal to our daughter when we are not around. Hopefully she respects our decisions and follows our plans for our daughter and doesn't go off and do her own thing when she watches her.
I personally would never start solids that early. That in my opinion is WAYYYYYYY to early. My oldest daughter started rice cereal around 5 months and that was only a small very watery spoon (about 3-4 spoonfuls) every few days to get her even used to the concept of eating period. She didn't really full out eat rice cereal until about 6 1/2 months old. My youngest was the same way except she didn't start full out eating anything including cereal until about 7 months. She really didn't have any interest into solids but now at 8 months is doing great. Some babies are different and some are capable of starting cereals in and around 4 months. I personally would not do anything earlier than that.

You could always lie to her, tell her you had some kind of allergy test that said she's allergic to it.
If she's stupid enough to give a 3 week old rice cereal, then she probably won't even realize that you didn't actually get an allergy test. hahahaha
