I have an Obaby stoller from dd1 and was planning to do exactly the same thing. I've just spoken to my friend (who has 7 yo twins) and she did it and has offered me her buggy board. Hers took turns but the board was a double step type one so they can sit on it too.
Hullo. I'm fed up with my twin buggy and now that the duo are able to walk a bit more I'm keen to see if we can use a single buggy with a buggy board.
I have a £10.00 single pushchair from Argos and as the weather has changed for the better I wanted to trial it with a buggy board.
I'm interested in hearing about experience of using a single pushchair and buggy board with 21 month olds (or thereabouts) and whether anyone has any advice on which buggy board is good. I would really rather not spend money on another buggy (we have previously invested in the mountain buggy with every possible addition and a city mini, I draw the line...).
