Bit of a niche one....anyone else's partner do seasonal work?!

[Tiredmamallama]

My partner does seasonal work and so is extremely busy in the summer and less so in the winter. Currently he's working 7am-7pm 7 days a week. Obviously he's knackered. I feel like I need to step up to support him but I'm also so knackered! We have 2 kids and I work 3 days a week too. How on earth do I juggle this? TIA

Save money in the winter when you don't need much childcare so you can get a summer nanny/babysitter to help at the busiest time? Or a cleaner/mother's help. Whatever would make things easier during the busiest period.
