How to deal with bedroom condensation/moisture on winter mornings?
Indoor humidity levels are high in the fall, making window condensation more likely. Where I am, we have to wipe our windows each morning for the first few weeks of cold weather. After that, it's less of a problem. It's important to exhaust moist air using bathroom and kitchen fans to reduce this effect.

Mold is a slight concern, but not as much so as during warmer months. More of a concern is liquid water damage. If water collects on the sills the wood will begin to swell and decay and the finish will degrade. This is your primary concern. If you wipe them each morning you'll mitigate the problem. 

If you still have regular condensation a few weeks down the road, look into the source of the moisture and whether you can improve ventilation or room-to-room air mixing (possibly using a fan-only cycle on your HVAC system). The appropriate indoor relative humidity level depends on the outdoor air temperature, so it needs to decline during colder weather.
