Rice Cereal did the trick. Thats right, we are now 4 days into adding rice cereal to the babe's eating routine and we have had 3 nights of sleeping the entire night!! It has been WONDERFUL.
The 4 month check up went well. The shots were no fun and the lil guy had a fever for the next couple of days. Aside from that, everything was right on track and we have a healthy, happy baby.
