Lan, What you need to watch out for is the possibility of D7 getting sucked into W's possibly dysfunctional emotional/mental world as she grows up. This can happen if they watch certain TV shows together that are not exactly appropriate for kids - of course this may not be the case with your W, but it was/is with mine - so much so that my D12 acts like 12 going on 21. As Sandi points out, kids, particularly girls, are forced to grow up too soon by TV and what they experience in and outside the home. I think part of the solution is to stay very connected and involved with your D7 and not leave it all up to W.
