I'm on the frugal end, not through desire to save money, just through not needing much.
Didn't use maternity clothes, just normal clothes. Used same normal clothes for bf.
Stuff for baby, was given a Moses basket, so bought blankets for it. Used pillowcases as sheets. I love charity shops anyway and they are awash with baby clothes so clothes from there, never more than 50p an item and I really enjoyed shopping for them.
Thought I would buy a pram/pushchair if I needed one, never have bought one so saved on that.
Did buy two wraps and a mei tai.
Did fb and when I had problems was given a breast pump and syringes to feed with, but did buy some milk bags.
Didn't have a nursery to decorate, dcs have gone into their own rooms around 1-1.5 years so not something done in pregnancy or new baby stage.
Bought birth to four car seat half price on kiddicare, but was offered infant seat from friends so could have saved there but I don't like the seats with handles as they hurt your back to carry and get overused!
Bouncy chair was grandparent gift. Baby gym thing was 99p local pick up on eBay.
High chair was bought at 5 months old and cost £38.
I was given nursing bras but bought button down nighties for nighttime co sleeping and bf.
Probably the whole pregnancy and baby kit and caboodle couldn't have been more than £400 spread over about 2years.
