Solids are usually introduced when babies are between four to six months old.
"Before four months, you run the risk of getting allergies and foods can be a choking hazard," explains pediatrician Dr. Jennifer Shu. "If you wait much longer than seven or eight months then babies get really used to full liquid diet and may have a harder time adjusting to thicker textures."
Doctors used to recommend a very rigid order for the introduction of foods, but that's no longer the case. Now they usually suggest that parents offer their baby cereal, fruits, vegetables, or meats in whichever ordert hey choose.

"When starting solids, it can be helpful to start the new food in the morning, that way a parent can watch a child for reactions during the day while the parent's still awake," says Dr. Shu.
"You might expect reactions, such as a skin rash or hives, vomiting, or diarrhea, if a child, um, has a food that does not agree with him.
