Shopping list advice

So I’m 16 weeks just going on 17 and so far I’ve gone a little overboard and bought the bottle accessories bottles etc ( curious how many bottles should I need if I’m breastfeeding and only pumping when I go out etc?) also I’ve got the nursery pretty much done apart from accessories etc so I’ve got the cot, wardrobe and changing table, a few white clothes ie onesies and body suits. Can anyone think of things I can buy before I find out the sex? I find out in 3 weeks so don’t mind what I can buy then too
