As long as you realize that formula and breast milk are the ONLY things that supply nutrition to your baby then feed them whatever you want. It will be empty calories that keep them from nursing or taking their bottle and getting food.
Cereal is to teach the baby to chew and swallow, milk is to feed them.
Baby food has about zero nutrition. It is a tool, not food. And that's according the baby food company themselves to me. I called to ask about some baby food that was given to me that was a couple of days out of date. The person at Del Monte or Gerber told me to toss it. That it has minimal nutrition when it's made then as it sits in the jar at the plant, in the trucks, in the warehouses, then on the store shelves it loses all that nutrition.
So we feed our babies flavored goo that has empty calories that turn to fat, we have a fat happy baby that's hungry all the time and eats and eats and eats and gets fatter and fatter.
We think the roly-poly legs are cute and a sign they're a good eater but it's not. They are starving all the time because they aren't getting any nutrients, the formula or breast milk they're getting is it, that's the only nutrition they're getting.
So they're starving for nutrients. Give your baby the bottle first, offer the breast, first. That whole first year let them drink as much formula/breast milk as they'll take. Then offer them bits of food.
