My daughter was similar to yours. One day just before she turned two, she decided she was no longer going to wear a nappy. She stayed in night nappies until we had two weeks of dry night nappies, and was then nappy free. We very rarely had a wet bed from her.

My boys however, were different and didn't want to ditch the night nappies for fear of wetting their beds. DS1 was nappy free by the time he was 3 even though he was dry nearly every night for ages. He wet the bed occasionally, and even now at 6 will have a wet bed every now and again. DS2 has only just agreed to no nappies (again, he's been dry at night for ages) and he's 4 in 4 weeks. He's wet the bed twice in about 4 weeks, but we have had a very stressful month.

I think if she's dry more often than not at night, then run with the no nappies. You might have a wet bed a few times but that's pretty normal! She will learn that it's uncomfortable and yucky to wet the bed and will get used to going to the toilet if she needs to or holding on until morning.

Mine only wet the bed during times of change/stress/illness and if they were extra tired, or if they fell asleep without peeing first. I always try to remember to have a spare sheet, blanket and clothes in a pile, ready to change them in case of an accident. It saves you fumbling about half asleep at 2am!
