We are not a bilingual family so she was not really introduced to Spanish until this summer and not much since the summer program. She clearly just has the natural ability to pick it up. Wish I did!
Mr W has not seen his "Spanish Grandma" for several months and we have not spoken much to him. Tonight she was over and they were all atwitter with each other. We have number of rituals we do with him in the evening and he was doing them with her in Spanish.
It IS pretty amazing how he can shift back and forth.
