stocking up???

37 weeks tomorrow and running out of time to stock up on diapers wipes other things. I currently have enough stocked up for about 2 months I think. is that enough?? how much stuff are you all buying in advance? this is my second kid and I had nothing stocked up with my first and I was constantly running out of things and having to run out to get new. I can't just go out to grab extra this time around because my husband is working long hours 6 days a week and we don't have any 24 hour stores where I live.how much are you all stocking up for?????? what's enough???
