Congratulations on your new baby!!
since you have had her just a few days shes probably trying to adjust to her new happy home. I'm not good at advising but to me she seems to prefer her run area at this time maybe because that's where she feels free and safe to potty. If she isn't using the house all over that's a big plus for the little girl
Sounds like you already love her so very much and she seems so thankful to you. She's following you so close just waiting to tell you she loves you too!!It will take time for you both to adjust but those days really do go by quickly and the reward is sooooo worth every effort you will ever make. Just think of all the snuggles and kisses she will give for your open arms to her!
