Did she just say what I think she said?

Jacey has been mimicking certain sounds with her voice.... It started with curious george, and mimicking monkey noises, and then she started mimicking the elephant sound that her bouncy makes. Now she says MA-MA and MA-ME (sometimes). Yesterday I said Bye-Bye, and repeated back to me BUH-BUH... Then this morning I said ba-NA-nuh and she repeated back to me na-NA-nuh... oh so cute :) Oh ya - she screams too... loud, piercing screams of delight!
