Welcome!! and congratulatons on your new addition!! when I first got Sami at 7 weeks he just about acted the way your baby is! I too have another yourkie Tilly 10 yrs and I think sami was a little afraid & intimidated by new surroundings & a new strange dog!
It wont be long before Lana will be attached to you, I sort of carried sami around with me alot and not really pushed sami & tilly togeather until He started to feel at home
So hang in there she will be so attached before you know it that your next post will be
(Help I cant go anywhere without Lana)
good luck &enjoy your new baby
