Night potty training - keep going or not

[DrWhooves]

I've been using the summer holidays to try night training 4.5 year old DD, been doing it for a few nights now. She's been dry in the day for 2 years so I thought it was time to try for the same at night. I've been lifting her at around 11pm for a wee, sometimes she has already wet the bed at that time, sometimes not. Even with the lifting she hasn't had a dry night and is always wet by morning, she is definitely wetting in her sleep because I've been going in to her early before she wakes so I know its not just letting go of a big wee on waking and forgetting there's no pull up there. We are going away for a few nights soon and I will need to use pull ups then as I can't deal with the washing there. If we haven't made any progress by then should I put her back in pull ups and try again in a few months or go back to pyjamas only? I've had mixed advice from other mums, some say keep going nappyless and she will get it, others that she isn't ready and bedtime pullups are no big deal, I'm confused about what to do for the best.

So I'm just making unnecessary washing for myself then? I'll add pullups to next week's shopping list then and try again in a few months, thanks.
