Addy loves to hold the neighbor's baby, Sienna.  She does so well with Sienna.  It gives me hope that she's going to be such a good big sister when her little sister arrives.  The several times I have babysat Sienna, Addy hasn't gotten jealous when I feed her or hold her.  I'm sure though that when the baby arrives and doesn't ever leave, there will be some jealousy.  Addison loves attention from mom and dad.  She doesn't play with her toys unless we play with her.  It's frustrating, but I don't know how to change that.
