I don't need another pushchair. I have my zapp which will do ds until he can properly walk everywhere.
But on a board for parents I don't think it is unreasonable to see lots of threads about pushchairs, prams and buggies.
We see lots about breast & bottle feeding - they don't interest me, but I don't have a problem with them being here.
We see lots about primary schools, but that doesn't interest me, doesn't mean they shouldn't be there.
