Bedwetting 3yo, put her back in nappies?

[JackBauer]

DD1 is 3.2, she has been out of nappies for about 6 months and dry at night for about 5.
The last few weeks she has wet the bed a couple of times a week. I have anti-biotics for her as I am fairly convinced she has a urine infection but her daytime weeing has settled down again to 2 or 3 times a day (she has always been able to hold it for ages, not like me) but yet she can't seem to at night anymore.
It is really distressing her, she is sobbing and clinging to me saying sorry. (I don't make a fuss, I change her and wrap her in duvet on chair while I change bed)

As she is only 3 should I put her back in nappies for a bit and try again when they have been dry for awhile or is this a backwards step?

(also she shares the room with DD2 and wakes her so they are both terrors the next day!

Shameless bump

Personally, and others may say different, I would not revert to nappies. DS has been dry at day and night for 10 months now and sometimes will have a couple of nights a week wetting the bed, maybe once every couple of months or so.

Did she get an infection diagnosis then?

If she has a confirmed urine infection then it isn't a big problem to go back into nappies until the infection is cleared, as the wetting is beyond her control.

No, she didn't get a diagnosis, can't get another sample to hospital until weekend by which time any infection will have gone and the first one was really watered down as she had downed nearly a pint of water
However, she was weeing and wincing every 15 minutes and was not right so I am fairly convinced it was one.

She is still dry in teh day, no problem siweht that at all, it's just every few days at night. Is it really that bad?
