Why can’t my baby swallow baby food?

Could be... ...A number of reasons: poor coordination of chewing, problem with throat or esophagus -- or, most commonly, just not being hungry enough.
Swallowing. The american academy of pediatrics recommends waiting until your infant is at least six months old to begin introducing solid foods. Babies are born with a sucking reflex, but getting food off a spoon requires a different bucal movement. Keeping solid food in the mouth and then swallowing takes practice. Make sure that you baby is ready.
