I'm only going to say this once. Your pediatrician is an idiot, please find another doctor.
Your baby is eating flavored goo that has NO nutrition in it at all. Nothing. It's to teach an older baby to chew and swallow.
It takes up space in their tummy and keeps them from wanting to nurse. They are starving for nutrition so they eat more food and it doesn't "feed" them so they want more. They look like they're loving it because they get fat. BUT they are NOT getting the nutrition they need.
You need to research this so you can make an informed decision. It's NOT good to feed a baby this age any solids at all.
It goes in, doesn't get digested well, sits in their tummy causing gas, when it goes in the lower part it can plug them up, cause diarrhea, cramps, and more. It doesn't give them anything at all.
If you research this you are going to be appalled your doc said to do this.
Babies don't even need baby food at all. They can even do totally without it until they're going to start eating table food.
Baby food doesn't have nutrition in it. It is flavored goo. It has minimal vitamins in it so they can sell it on food stamps and get parents to buy it so they stay in business but it's NOT FOOD!
