S.O.
The best strategy is to simply talk with her. I wouldn't worry about flash cards but rather just incoporate conversation into her day. While reading books you can ask her about the pictures, characters, etc. and do the same thing as you do things with her. When you ask her a question and she answers, repeat her answer while expanding on it at the same time. For example "What do you want to drink?" She may say milk then reply You would like milk to drink or aske her to say "Can I have milk?" The more language she hears and is exposed to, the more she will progress with her language skills...just talk to your child!
