Baby food has almost no nutrition to them. He wants to nurse because he's starving for nutrients. Feed breast first please. It has everything he needs. Then let him have some foods. Food at this age is ONLY to teach him to chew and swallow without choking.
So many people think feeding them food is good because they get all chubby and cute. They get fat because the food isn't food and it turns to fat. Breast milk and formula has 100% of the minerals and nutrients babies need that first full year.
This information is straight from the horses mouth. I called either Del Monte or Gerber to ask about stage 3 baby food that had been given to me but it had expired the week before. They told me I could use it but it had zero nutrition in it and it would be like feeding the kiddo flavored goo, not food.
She said that the food comes off the line as a good source for teaching the baby to chew and swallow but it has very little nutrition in it to begin with because mom's are supposed to nurse or give the baby a bottle first. As the food goes in the boxes then onto a truck then into a warehouse to sit and sit. Then back on a truck to go to the store where it sits on a shelf in the back, until the jars in front of it get sold. Then it's finally sold and fed to a baby.
The jar is glass, light gets through, the food deteriorates this whole time, losing its minimal nutrition before it's ever bought.
It's not unhealthy to feed to a baby...it's just not nutritional. It's a tool for teaching.
Formula or breast milk FIRST so he won't be starving.
