So it’s been a week. Riker is pretty much integrated into the family: not afraid of much, goes where he pleases, and demands play time. Mara is still pretty shy and keeps to herself.
We finally gave up on Mara hiding constantly, so all the books on the shelves were pushed back to the wall, cutting her hiding places to just a couple. She let me pick her up yesterday and I was able to hold her for a bit. After a slightly traumatic fall from the top level of a bookshelf, she’s a little shy of heights at the moment.
