Keeping maternity clothes

So I have a 2 year old and a 4 month old and am done with having babies for a while. I know i want one more baby but not for a few more years. I kept all my maternity clothes since my 1st pregnancy and used them for my 2nd pregnancy. I just cant let them go😭. I thought about donating them or selling them but i just can't. Lol I'm weird 🤦 I have a lot of clothes, like overflowing basket and trash bag of pregnancy clothes.
