Bed wetting, advice wanted

My daughter just turned 4 in August, she hasn't worn a pull up at night now for while, maybe since June, obviously there were accidents, but not a huge amount.

She started school in September and bedtime accidents are now at least every other night. I try not to let her drink too much before bed, I'm also confident she doesn't have a UTI, I'm sure it's to do with the big change of starting school.

She is not too upset about the bed wetting itself, but that she's waking up cold because she's wet. I feel like going back to bedtime pull ups is a step in the wrong direction, but last week it was pretty much every night she wet the bed.

But my question is what would you do? Suck it up and continue as is, or go back to pull ups? Any other ideas?
