Weaning

Hey, just looking for a bit of advice, I starting weaning my baby two weeks ago,I have been giving him the milipa sunshine orange or milipa bedtime cereal, I give him about 3 tablespoons of each, the problem us that he always looks a bottle about an hour after eating and he will drink between 4 and 6 oz, I always thought that when that had solids it would fill him for the same amount of time as a bottle, I don't know if I should give him more cereal or not as I'm not sure if it would be too much for him. He is my first baby so I'm completely new at this, any advice would be much appreciated. Thanks :)
