not sure if she is old enough for this to work.....my oldest was almost 3 when baby brother came along. since infants naturally squeeze things w/ their fingers, we told our oldest to stick out his finger. when he did this, the infant squeezed his finger. and (as planned) everyone in the room reacted "oh my" "wow"....we told the oldest that when the infant squeezed his finger, it meant that he loved him and that it was special that the infant was "giving him hugs and saying that he loves his older brother.".... also, when the infant is crying (and doesn't need immediate attention) and you are doing something w/ the oldest, say out loud "just a minute (infant's name), mommy is doing something with big sister right now." wait a few secs, then get the infant....just hearing this will let the oldest know that she is still important and that you won't going running everytime the baby fusses. good luck!!!
