G. Aunt Pat and G. Uncle Ron sent a photo of G. Uncle Ron reading a book to Zoe, and I hung it on the bulletin board in the kitchen that Zoe can see from her high chair. There are probably a dozen or more photos of Zoe on the bulletin board, but she picked the new one out right away without anyone mentioning a thing about it. She pointed at it and said, "That's Zoe and Uncle Ron!" Now she has to point at it every morning and say, "Uncle Ron!" I need to hang this photo up so Zoe can point at Aunt Pat too.
I've gotten in the habit of telling her who has given her which toys when she is playing (and also who's given her which clothes when she gets dressed) so she realizes that even though all her family are not close enough to see her often, they all think of her. She pretty much remembers everything, so now when she is playing with a particular toy she will say on her own something like, "Ron and Pat give you that" or "Grandma and Grandpa M give you that."
