i guess i would try to speak to her in spanish sometimes. maybe even mid sentance or something? for kids its incredible how quickly they learn other languages (which makes me so frustrated that most schools around here dont teach it until high school. i had it in high school and it sucked!!) she can learn them both fluently at the same time. she looks at you like you are nuts when you speak spanish to her because shes not used to it coming from you i guess LOL
but yeah, just keep doing what you are doing, and try to add some spanish from you. :)
good luck! :)
