The only advice I have is that anything that has elastic and you don't need it - get rid of it. I kept so many things after I had our first baby (a boy) hoping I could use them again, then we had a girl second and used some of it, but I still kept all this stuff JIC the third was a boy, but when I got it out, all the elastic had perished and was no good anyway. All that time it could be been used by someone else and now it couldn't. Things that had elasticated waists etc.
