Welcome to YT. Glad you found us!!! Your baby is precious! I am not an expert, but I do believe that it is normal for your baby to attach themselves to one person. I have noticed with my yorkie and others that I have been around that they are very loyal.
My son tries so hard for our little yorkie Roxee to stay with him. We put Roxee in his lap, in his arms, on his bed, etc and she will stay only until she sees her mommy. Roxee is 1, and she really recently started to really like my husband. She always liked him, but not if I was around. Within the past several months, everynight she will sit with him while watching tv.
I think it will get better, although you will probably be her mommy!!!
I tell my children, there is nothing like a good mommy!!!
Good luck and please keep us posted on your baby! Maybe someone else on here will have more information on this.
Thea and Roxee
