Night dryness regression

[sugarplum33]

My DD is 4.5 and has always been very easy with toileting. Dry in the day before she was 2 and dry at night about a year later. She had always got up in the night and taken herself for a wee and gone back to bed without issue and in a year and a half I could count on one hand the amount of times she's ever wet the bed. We've been on holiday and stayed in different places and she's always been just as reliable.

About 2 months ago however she started wetting the bed a few times a week. When this continued for a couple of weeks I got her urine checked and she had a very mild UTI. This was treated with antibiotics and has since cleared up but the bedwetting has continued to get worse and she's now wetting most nights. I've had to put her back in pull ups which she's accepted but I'm concerned why after all this time being so reliably dry she has regressed so dramatically. I'm due our second baby soon so I wondered if it could be linked to that but it doesn't seem to quite add up. She doesn't like the wet pull up so will change it by herself in the night and put a fresh, dry one on and she is very pleased about any dry nights she does manage so she really doesn't seem to be choosing to wet herself out of laziness or for any attention.

Everything I've read suggests that night dryness is hormonal so I'm confused how and why she has lost that after so long. Has anyone experienced this?

Did she start school in September? It's probably that combined with the new baby arriving.

Thanks for the reply, no she's starting school this year and nothing else has changed. Couple of dry nights since this post but another wet one last night.
