Homemade Yogurt II

Having made plain yogurt successfully, I became more adventurous and decided to try it out with strawberry milk :)
Again, I like to serve it with fresh fruits.

This is already the 3rd batch of my homemade yogurt from the initial starter yogurt. The yogurt became more watery on each new batch made. I suspect it's because I didn't add any dry milk to it. Nevertheless, kids love it and kept asking for more.
