Do we really need a new mattress? Annoying to have to buy a new one!
There will be 6 months between my two so we might need a few new clothes if the size isn't right for the season. Also DC1 is a boy and DC2 is a girl, all the baby clothes I bought were unisex and we got some more "boyish" clothes as gifts - I am sure I will reuse most of them for DD anyway but I am also looking forward to buying a few girly things, not necessarily pink but one or two dresses and floral prints.
Apart from that we have virtually everything we need. We had an ergobaby for DS that we will reuse, also a friend has offered a soft stretchy wrap which I will take her up on as I imagine it will be useful for the early days.
DS will be 3.5 and we barely use the pushchair for him (apart from occasionally, as it's handy for lugging stuff around) so I don't think we need a double. I will probably get a buggy board though, maybe a second hand one in case he doesn't take to it.
I will get a chest of drawers for baby's room but that's the only big thing.
Need to buy a new single bed for DS, so we can use his cot bed (currently in toddler bed mode) as a cot for baby. She'll be in his old Snuzpod to begin with though.
I do feel a bit sorry for DC2 getting all of DC1's hand-me-downs and barely anything new! Also in my first pregnancy I wanted to buy new, not used, but now if we need anything else I will consider used. To be fair that is because I always knew I wanted two, so anything we bought would be likely to be used twice over (whereas anything we buy now will just be used once).
