Winter biking with kids in trailer?

[Irulan]

Having taken kids XC skiing in sleds, here are a couple of things to think about
-they will generate very little of their own heat, so insulation is foremost. Think something like a sleeping bag as you do not want to constrict them.
-Extremities ( hands) are really prone to getting too cold as they like to pull them out of whatever you've bundled them it. This is why a sleeping bag type thing is good, you can close it up around the neck so the hands stay IN and WARM.

have fun

I'm in WI and tried it with my son when he was 3 - he hated being in it in the cold weather. I tried one of those round thermal heat pads the ice fishermen use for him to sit on but couldn't get him comfy enough.

So I waited til he was 4 and got him snowshoes He LOVES those!

+ 1 on what Irulan said. You will be generating lots of heat while they're just sitting still, so more insulation is required than you'd think. A sleeping bag sounds good. Remember it gets compressed underneath, so an extra layer of foam pad or something to sit in or underfoot is good. A quick way to add heat is just find a non-leaky water bottle and add as hot water as the material allows. Put it in a sock if it's hot enough to burn, then put it inside the sleeping bag or blanket. Refill with warm water anywhere you can if you're out for a while.

Here they typically say to keep outings to less than an hour, hour and a half if the temperature is below -10 C, and to not go out at all with small kids below -15 C (with kids sitting still in ski-sleds that is). I was also told that a good way to check body temperature is by feeling the back of the kids neck.
