We bought:
New cot (sold it still in its box as accidentally co slept!). Ikea.
New playpen (sold after being 'used' twice as child screamed blue murder going in it)
Some new clothes
New high chair (Antilop)
Playmat (Ikea)
Second hand moses basket (then never used, see above)
That was it. Oh, new pushchair.
We didn't buy a whole heap of stuff, didn't decorate a nursery. Child is 3yo and about to go into their own room - which, surprise surprise, still isn't really 'decorated' as such. One bed (new), some pictures, mis-matched furniture (2nd hand).
Neither DH nor I have rich rellies desperate to buy big-ticket items. They bought the odd babygro or cute outfit, as did friends, and things such as stuffed toys. We didn't go nuts either: we bought everything for around €400 including pushchair. Clothes mostly from Primark as they get vomit and shit all over them when they're tiny.
Child wore the clothes we were given, even if "not to our taste" - who gives a shit? They're clothes. A child is a child, not a fashion accessory.
Announcing you're buying everything new seems a little boastful to me. "We can afford all new... so... er... that's all. Carry on."
Oh, and ditto TropicalHorse
