Jen, my kids might not always be well behaved, but they do always have good manners Or nana's as Noah calls them.

When I give them something I simply say thank you mummy, to Teh or my little ones when teaching them, Teh for the most part doesn't need to be remided anymore. And if they ask for something I will say "cheese, please mummy" and Teh will repeat it back. I only do this if she has forgotten though. I do expect her to have times when she forgets, as adults there are occassions when we may forget too.

Teh, used to say " 'muse me for parting" that doesn't happen often enough lately, usually it's giggles and her saying "Mummy, I parted" !! I guess that's what we get for having a household full of males that think farts are funny.

Consistancy is the key, just like when you are teaching your children anything. She will learn and it wo't be long before you are getting ta's for everything
