My doc told us to stay on cereal exclusively till 6 months. If you start them on other foods too early they may not be able to digest it properly, or can even develop food allergies. We kept our dd on two cereal feedings till 6 mos. She had cereal in the morning and again at night. I would make a 6 oz bottle, use that to make the cereal, then give her what was left. If she acted like she wanted more bottle, I'd make another 2 ozs. If you do decide to start him on other food, make sure to start the veggies first. Also, make sure that you do single veggies first. No mixed veg or garden veg till he's had all the veggies. I would also recommend starting on squash or sweet potatoes. The green veggies are a little too bitter. Good luck!!!
