Wanted Children’s Lifejackets

I’ve got the grandchildren coming for a week at Easter and as I have a Kayak, I think they would love to “have a go” but I wouldn’t dream of letting them go in it without a lifejacket, even though they are all good swimmers. So, I’m looking for a couple of lifejackets approx age 5, 12 and 15.

If anyone has any hanging around, I’d be very interested.

Thanks in advance.
