No kidding, I bet you are. Well Harvie is only 3 months at the moment. When they are at this age they are still expected to have a night feed still in some babies. Harvie though is sleeping through. He is a good weight though. 6.5 kg. His body weight can sustain him through the night. (I also put a teaspoon of rice cereal in his 'dream feed' bottle at 10 pm.)
Babies your lo's age should sleep 10 to 12 hours a night. I follow the E.A.S.Y (Eat, Activity, Sleep, Your time) plan laid out in Tracy's book and it seems to work a charm.
