Yobaby is a brand made by Stonyfield. It is a full fat yogurt. CritterMom highly and alsways recommends the Yobaby brand, and
whatever CM says is "golden" in my book. So that is what I now use... part of CM's recommendation is because the squirrels seem to like all the varies flavors; I have found this to be very true. It is also organic and has no added sugar.
(The real reason CM may recommend this is because it is the only brand of yogurt CM, an avowed yogurt hater, apparently likes herself!
Or maybe she owns Stonyfield stock?!?

Those first two pictures, she appears to be about 6 - 7 weeks to me. They do have lots of dreams at this age, so hopefully what you are observing is squirrelly dreams. Continue to keep a close eye on her though as sometimes issues from a fall like that may not show up for quite a while.
