I would say we started buying bits and bobs around 17 weeks when we found out gender. But started seriously buying the big things once I was 30 ish weeks.
I would say essentials are
Moses basket/ crib
Cot
Pram (travel system with car seat and basket)
Lots of bath stuff- cotton wool, shampoos, baby bath thins like that etc
Stacks of nappies
Lots of baby wipes
Lloyd went over board on clothes and bought up until 9-12 months
I got baby grows, vests, bibs, dresses, outfits, socks, shoes, coats, snow suits etc
Blankets/swaddlers
Cot bedding etc for bed room
Swing
Baby bouncer
Sling
Breast pump
Steriliser just incase and a few bottles
Angel care monitor
Lots of other things
I honestly have no idea what I spent but it was ridiculous probably 3-4 grand?
This time we are being less ridiculous as I've realised baby doesn't really need all the high tech equipment etc so we are getting
Co sleeper cot
Unisex clothes baby grows/vests/bibs
Unisex blankets
New breast pump
New bath stuff and baby bath
And a new seat for my pram I have one that can go to a double and I think that's pretty much it.
I would say it depends on budget because it depends on what type of pram you want? You can get one for over a grand but then you can get some for a few hundred so that's a big part of the budget.
Also depends on how much you are spending on cot and doing up the bedroom etc xx
