Inexpensive waterproof trousers for 18 month old?

[Cratchit]

Please help?! Has anyone seen any that aren't horrible colours or outrageously expensive? Ideally want to get a couple of pairs for DS as he's still crawling like mad and not quite walking yet. Winter's looming blah... Also open to waterproof dungarees or all in ones. Have seen some in mothercare but they're £18 or something and would like to try and find cheaper.

Tchibo had some a week or two back but think sold out quickly how about these but smallest is 2/3 or these ,or these . TKMaxx and TJ Hughes sometimes have them too.

Millets? Under £10 I think.

Millets ones are excellent, but I think their range is wider for girls in terms of design choice...

Lidl are doing waterproof clothing for kids next week - I've bought their dungarees in the past and they are fantastic quality (they're also doing raincoats/capes/wellies etc.

Huge, if belated, thanks to all. Been to Lidl - Hooray and haven't broken the bank.

A bit late Crachit but would you like a red all in one? I have one and no-one to hand it on to. It cost me very little on ebay - has one small white mark on it but is otherwise in fine nick. If I can find it it has a grey fleecy all in one to go underneath, for when it's really cold. If you cat me you can have it.

Womanwhothoughtshewashat - I'd love them if you're still around and they're still on offer. I've tried catting you but can't make it work with your nickname.

muddlepuddle do them and they're great
