FTM asking.

What are some items that we can safe for next baby? I was told by a friend EVERYTHING can be used again including bottles 🙄 I have a 1 yr old daughter and everything we have gotten her is girly so of course I won’t use any if I get a boy lol but besides that can we keep everything? Bottles idk I feel some type of way lol regarding hygiene even tho I sterilize after every use. I’m also concerned storage wise it’s a lot we have gotten her and also family have gifted her. How did you keep everything? Concerned storage wise.
