Can i give ripe mangoes to my 8 month old?

Maybe not: Fruits which are very acidic may cause face or body rashes, diarrhea, or diaper rashes in babies. Some babies will have reactions even until 2 years old or so. I would be cautious about introducing orange juice, mango, pineapple, etc. In the first year. When you do start these foods, start with a very small amount and then watch your child for a few days afterwards to see how she responds.
