Hi,
I only kept the ones that were sentimental, like the outfit he came in and others that were special. You don't want to keep them all or you will end up with no room. You can always give to someone that really needs them and doesn't have the money. You can also have a garage sale and offer them that way. I do have some of his clothes from a baby that I kept but I didn't keep them all. There really isn 't any point. My MIL kept a few of my husbands clothes and gave them to us when my son was born but they were old and the elastic didn't work anymore. They really for looks when they kept that long so I only kept a few things. Good Luck on what you decide.
