Congratulations on the addition to your family! What an exciting time!
I always recommend, if you haven't read it, Parenting the Hurt Child. I think it's such lifesaver with older child adoption.
I think beginning schooling and language learning can go hand in hand. For example, if you're learning to count with objects, you're working on English and beginning math. Really, all kindergarten math is basically vocabulary. Also colors, shapes, maybe setting the table and folding clothes. Reading beautiful books together. I think you'll have lots to work on for a few months while she picks up English. By then she'll be ready for 1st grade when "real" academics start.
I'm so happy for her and you!
