A few months ago I visited a 'parent centre' when I was out of town (I remember where exactly I'd gone ... maybe to my sisters ... anyway ...) and if the adults wanted a drink while all the kids were playing they were provided in these excelent safety mugs.
It was traditional mug shaped but had a concave lid with a small hole in it so that if the mug was knocked over, only a small amount would gush out, allowing you to reduce the risks of burns to little people. It wasn't like drinking out of one of those horrid fast food coffee cups because the concave lid let it flow into your mouth just as it would from a normal cup.
What's more, there was a little sliding device that enabled you to seal off the hole altogether, making it spillproof so if you needed to run after your child you could put it down and not fear it was going to get knocked over.
I THINK it was slightly insulated as well - it certainly wasn't hot to touvh on the outside and my tea stayed warm for a lot longer that it would have done at home.
Having gotten used to cold tea (I think that's a Mum thing) I found this hot tea lark quite exciting and am now desperately hunting for one of these mugs but hours of googling have got me nowhere.
Does anyone know what they're called or where I can get one? Or if it sounds familiar at your local parent centre could you tell me where I was so I can ring them to ask !
