Your opinion on the best cup to take to bed?

I have a few different brands of sippy cup, but they all leak.
I want something DD can take water to bed in and not wake up with wet pillows/sheets etc., as she insists on cuddling hers.
Any suggestions to check out would be appreciated.
:)

maybe the kala cup?
i find they all leak too, but this ones seems to be ok! can get them from babybunting! the tops also fit onto normal water bottles too and can be bought seperatly

Yeah, I like the kala cups too, although I find the seal between the top of the cup and the lid does sometimes leak. However by putting the valvey thing on a water bottle you eliminate that problem. And you can buy the valves separately. Our chemist sells them (Soul Pattinson).

How about an empty cup or one with a very small amount of water? This will make it much easier when you're up to toilet training.
