Am I being selfish?

M

I have a lot of baby clothes that my son has outgrown and most of them I got from my baby shower and his first birthday party (a lot of people attended both) and some that we bought for him as well. So I just have them stored in bags on top of his closet. My husband keeps saying I should just give them all away but I don’t want to get rid of all the clothes because we plan on having one or 2 more babies and I want to keep clothes in case we have another boy. There are neutral pieces that a girl can wear and I want to keep those as well. My brother in law and his wife are currently expecting but don’t know the gender yet and if it is a boy my husband will want to give all the clothes to his brother. I’m planning on giving them a lot of clothes but not all. I want to keep at least half and also my favorite pieces. Am I being selfish? My husband says I’m being a selfish person and I shouldn’t be like that but I want to keep them until we decide we won’t have more children. Once we decide we won’t have more I will give them all away because I won’t have any use for them anymore. I’ve told that to my husband but he keeps on saying the same thing 😑. Any advice?
