Congrats on being a home-owner!!! i am so jealous!
Tucker and i recently moved to a rented trailer. my former landlord decided he didn't want tucker in the house anymore. anyway, our biggest problem was with the pottying. i trained tucker to go outside, but this is an old trailer with lots of interesting scents, i'm sure, and so he is having problems with that
he wasn't really scared of the new place. i guess cause it was all the same old stuff- just in a new place. so maybe if you surround your babies with familiar things and set boundaries, they'll love the new place, too. it's good that you'll be home with them for a week. i'm sure that will help a lot!
good luck!
