There are a lot of baby-friendly foods out there, but after years of analysis, here are a few recommended foods that stand out from the pack.

Bananas: Banana is a good source of carbohydrate and it is considered the grab-and-go fruit. This fruit also contains high levels of vitamin B6 and vitamin C, iron and calcium. Bananas can be made into a puree/smoothie, which makes it easy for digestion.
Recommended age: Four to six months

Sweet potato: Okay, so there is nothing called “Super baby food”- but sweet potatoes are something that comes very close. They are the most nutritious food for babies since they have high levels of beta-carotene which when ingested the body converts into vitamin A. Vitamin A protects the baby from infection, also important for good vision and healthy skin. Potatoes can easily be mashed into a texture that is easy for babies.
Recommended age: Six months and older

Lentils: Lentils like beans and other legumes are a good source of lean protein and fibres. Proteins known as body building food, a regular source of protein will help the baby grow strong and healthy. Beans boiled and mashed with vegetables like carrots and beets will make it easy for digestion.
Recommended age: six months and older

Yogurt: Creamy yogurt is rich in vitamin D, calcium and iron, necessary for the healthy growth of bones and teeth. It is recommended to opt for plain yogurt without any added flavours or sugar. Yogurt also has probiotics, a type of good bacteria that helps in digestion and also improves the immune system.
Recommended age: Nine months and older

Iron-fortified cereal: Babies are born with a natural supply of iron, but these levels get depleted by the time they reach six months old. Rice cereal that has a high source of iron, oatmeal and barley are also good options. High iron levels will keep the baby strong and healthy.
Recommended age: Six months and older

Bottom line:
Babies constantly require a high source of fats, proteins and vitamins, but remember that the food must also be easily digestible and edible.
