We make our own with an easy yo, but use natural yogurt as a starter, not the packs. You can also make it with breastmilk instead of cows milk
We like easy yo too- full fat Greek. When I first started DD on yoghurt, I bought Greek yoghurt that's about 10% fat and really mild and creamy. DD occasionally gets vanilla yalna but I recon babies don't need foods sweetened to eat them.
