getting to work in the snow and ice is a little tricky yes, but I just allow myself longer than normal. Childcare is never an issue, me and my partner work opposite shifts so there's always one of us at home. Weather doesn't really put a stop to any activities, swimming is indoors, soft play is indoors, the local leisure centre has a kids section that's indoors, even nature walks are still fun, just wrap up warm and get on with it. If the weather is really too bad, we do lots of fun things indoors. My eldest is autistic and also doesn't like the heat
Do you live somewhere where the winters are very mild? Being cooped up indoors in germ-infested soft plays is not my idea of fun, and there's only so much swimming you can do. Nature walks might be fun if the weather is dry, but let's face it - nature walks (when there's very little nature about) in torrential rain or ice isn't fun. Playing indoors is fine for short periods, but children need fresh air and exercise, and if you're working 48 hours per week plus your long commutes as a result of the snow, ice and general disruption that winter brings then there must be fairly limited time to get outside.
Spring and summer offers far more in the way in opportunities to be inside if needed, and outdoors enjoying the light and fresh air the rest of the time. The UK rarely gets so much hot weather that means looking forward to months of cold, miserable weather. We certainly don't get many crisp, cold days - it's endless damp.
