yeh charli there is always numerous stands on ebay - they are often pickup only so it will depend on where you live - otherwise I think the baby stores could order them in - I haven't seen them in the general department stores.

Gabysmum - I put Samuel in for a similar reason - DS1 was happy to just lie around doing not much but young Samuel is much more of a goer and likes to stand or sit upright (in fact will lock his hips and knees to prevent you sitting him or lying him down easily on a very regular basis).
