About £80 on eBay for a massive lot if baby stuff including cot, moses basket, bouncer, bath, top and tail bowl, curtains, nappy stacker, changing table, toy shelf thing, full set of cot bedding (sheets duvet 4 blankets bumper etc) and a few other bits I can't remember. They were all matching in cream and probably cost a fortune when new.
Paid about £60 for a new mattress for the cot.
Bought another basket and a couple of Moses basket stands second hand so we could have one upstairs and one downstairs for DS2 (when DS1 was a baby we were in a tiny flat with no stairs so just carried him / basket around). That was probably another £20 plus a couple of new mattresses for them, £10 each from amazon.
I went on the basis that they will only need those things for a very short time and they (or anyone else) would have no idea it wasn't all brand new!
From the bundle of stuff we bought I discarded lots of it pretty early on anyway so that would have been a bit galling if I'd bought it new.
I am sure there will be other times in their life when the £1000 or whatever will be needed more. Or spent on something they would enjoy more. That could buy them their first car. Or pay for a really brilliant family holiday!
