Hello J.,
i started my kids both on single grian rice cereal, and they both actually started it at a 7 weeks, i started out with cereal in a bottel, and i actually had gotten cereal bottels, which help your child get the swallowing down because you can make the cereal pretty thick in those bottels, but in a regular bottel you can only put like a tsp in at a time because the nipples get clogged. i had a problem with my daughter on the rice, it made her constipated, and so i switched to barley and that really work for her and then i moved to the oatmeal with her, my son is having no problems on the rice, i'm going to be starting him on the barley this weekend actually, and i'm sure that he will be just fine, but after my daugther got to the point of really swallowing, i starting giving it to her in a bowl, until she got on furit, i only gave it to her twice a day, once in the moring and then right before bed with her night time bottle, but when she got on furit, i would feed her like 4 times a day once in the moring with cereal, in the afternoon with furit and cereal, dinner with furit and cereal and then at bed time with just cereal, it was great, and when my daugther got on cereal she started sleeping 12 hours with no problems, my son sleeps any where from 8 to ten hours at night so i love cereal, i hope that you have just as much luck on the cereal as i did
Good Luck
S.
