The Winter sports season starts mid to late December, depending on the amount of snow. I don't know the area of La Barboleuse that well, but there most probably won't be snow in the village around that time as it is located at only 1200 m. Whether the surrounding slopes are open by then I don't know, you can best ask the local tourist office. They won't be able to guarantee anything, but they should be able to tell you when the season usually starts.
To enjoy snow early in the season your best bet is to either go to a town surrounded by really high mountains (Zermatt, Saas-Fee), or to wait with your booking until a week before so that the weather conditions are predictable. If you're lucky there will be plenty of choice, if not you can still consider one of the higher towns. Mid December isn't high season yet, so booking late should work.
