What products should i rebuy and what can i reuse from my first?

I had my first son almost 4 years ago (well by the time I have this baby it will be just a few weeks before my first turns 4) and I have saved everything I possibly could. I am going to buy a new swing just cause there are better models out now that hopefully wont break as easy but aside from that im unsure of which products we should rebuy and what is okay to reuse. I am just going to get rid of the old bottles and rebuy those as well. We dont have a lot of money right now so whatever I can reuse would save us money. Also what are yalls opinions on cloth diapers and now do you clean them? My toddler still is in diapers (refuses to potty train but thats a whole other topic) and its so ridiculously expensive and I really dont want to have to buy diapers for both so ive been looking at cloth diapers but my bf is grossed out by the aspect of cleaning them
