@Victoria~ yogurt has a much smaller level of lactose than milk and the active bacteria is also helping the body to digest food. So milk and yogurt aren’t the same things because of the chemical process milk had to go through to become yogurt.
i gave my daughter plain whole milk greek yogurt from the start and she loves it, even now at 2
Sugar free natural yogurt or Greek yogurt is fine! Try to avoid sugars.
The best yogurt for baby is probably none
Greek yoghurt with fruit puree
Natural yoghurt or Greek yoghurt full fat
