While it is true that the medical community recommends avoiding drinking cow's milk until your baby turns 12 months old, that does not mean that all dairy foods need to be avoided. In fact, certain dairy foods should be a part of baby's diet starting at 6 months.
Whole-milk, unsweetened yoghurt is an excellent first food for baby and can be eaten safely at 6 months of age. The proteins found in yoghurt are easily digested by baby and the vitamin, mineral, and nutrient amounts are perfect for what baby needs — like calcium for strong bones and teeth. Yoghurt's texture is also appropriate for babies exploring foods for the first time. It also naturally contains live probiotics which can help support a healthy tummy and immune system.
Start by feeding baby yoghurt on a spoon. Once that is accepted, try mixing yoghurt with other purees. Whole-milk, unsweetened yoghurt and pureed banana seems to be a favourite among the baby community!
