Our second child was another daughter but we weren't aware we were having another girl. Before she arrived we bought:

- a (Maxi Cosi) capsule. Didn't have one with DD1 and so wish we did!
- a new pram, the City Select so DD1 could still ride in the pram and we could connect the capsule at the same time.
- a bassinet. We borrowed our first one and it was tiny. DD2 was in our Boori bassinet for just over 4 months
- big girls bedroom suite for DD1
- a new monitor for DD1
- another sling
- summer neutral 0000 onesies as DD1 was a winter bub

I bought extra bibs and spew rags once DD2 arrived. DD1 wansn't a chucker at all so the supplies we had for her didn't cut it at all. You may get a non-chucker this time so I'd hold off on the bibs. They were a total waste with DD1.
