Hi Kate,
My ds will be 2yrs 9m when bubba arrives (also in May!) and personally I'm going to try the buggy board idea.
My first pram was blimmin expensive and would love to use it for my second.
I like the idea of getting him used to walking a bit more, I do try now but he tends to want to be carried, unless he has a train to hold!! hehe!!
