The fleece under layer is like a fleecy onesie with a zip for quick on and off and poppers to open up the leg area. Can you see that the cuffs around the legs and arms are extra long? That's so that they actually last for more than a few months; when it's big for the child they are folded over and as they grow you just fold less and less.
The waterproof and windproof 'overalls' are worn over the top along with a 'fuskolle' which is a turtleneck jumper minus the jumper: you can see it in the top left of the picture. I had never heard of a fuskolle before my husband introduced me to them but OMG they are brilliant. Why wear a scarf when you can just slip on a bit cut out from a woolly jumper? Genius those Swedes.
The rest is pretty self explanatory really - furry windproof hat that actually covers the ears too, waterproof snug snow boots and gloves that have zips down to the fingers so that you can get little fingers into the right places.
The Swedes have a wonderful expression which is "there is no such thing as bad weather - only bad clothes". So true.
