Hi! Welcome to YT! I have had to deal with jealousy issues with my two girls. I will be honest, it is a challenge. But can be managed. Many others on here gave me lots of advice on what to do. Here is the thread I started and the advice others gave to me.
http://www.yorkietalk.com/forums/con...l-problem.html Hopefully you will be able to find some of their advice useful as well.
Now on to the other situation. When we first got Rosie she wanted nothing to do with me. Only my DH. I was so upset. It really really bothered me. With that said, she is now the biggest mommy's girl ever!
Give it a little time, you might be surprised what happens.
Again, Welcome!!
