What does your toddler wear in the snow?

Em

We are going on a trip to a snowy place. My son will be 18 months when we go. I’m hoping not to spend too much money but want to make sure I dress my toddler appropriately as I’m from somewhere that never snows. If you’ve visited the snow or live somewhere that snows- what shoes does your toddler wear? Trousers? Jacket?

Most importantly- Where do you buy reasonably priced snow gear for toddlers?

Thanks!
