Ok, I'm no expert so I'm sorry if I get some of this wrong!!

At her age she doesn't nutritionally need it. She may get thirsty (especially seeing as its summer!) so offer water if you like. Its comfort so she will need lots of cuddles! But you know that

Ive just recently night weaned Eva (at 13.5 mths) so I'll tell you what we did. I did the same thing with Darlie (but at about 8mths I think)

Before we weaned she would sleep in her cot till she woke (sometime after midnight) then I would feed her and bring her back in with us.
We began weaning when DH was on holidays so he could get up to her that first wake-up, so he could get her back to sleep without a feed. If she woke after that, he would bring her into our bed and I would cuddle her but not feed her. Surprisingly this worked well! It only took a few nights and now she is even sleeping through!

It wasn't really traumatic either - she grizzled a little bit the first night wanting me instead of DH- but she never had to cry herself to sleep or anything.

Just know that its ok if you want to night wean - you aren't a bad mummy or anything! Youre doing a great job
