6 months is old enough to start giving your daughter rice cereal off a spoon. You do however only want to start with a single grain cereal (it should say so on the box). Because if you get multigrain and your daughter is allergic to one of them you will not know which one. I am also a first time mom, I will be 27 in a month and a half, and my daughter Kaydence, will be 2 in April. What you do is mix some of her formula with rice cereal, make sure its fairly runny though, since they dont really know how to work a spoon yet and its less of a chance they can choke. You can do this 2-3 times a day, usually when you would give her breakfast, lunch and dinner. And its also great if you baby is not a good sleeper b/c this will fill them up a little better before bedtime and they may sleep thru the night better. If you have any questions, you know where to find me. Good luck!
