Sorry your babies are having digestive problems.
Is there a reason you feed them grain free kibble and add fresh foods & cheerios that are grains?
When it comes to digestive problems, I would keep the diet very simple. Cut out all of the snacks. See how they do eating just the kibble, then introduce one item at a time.
Teddy is sensitive to many foods, so I keep his diet very simple.
