Night weaning is pretty simple, but not very pleasant. Feed her more before bed, both solids and bf - then when she wakes in the night give her a drink of water and a cuddle and walk around for a while and somehow get her to go back to sleep without bf. Much better if you are not the one doing this, as the smell will make her want it more.
This might be an easter holiday plan - for a few nights at least you will get even less sleep than you currently do!
