Keeping or giving away baby things?

Da
Just wondering for those that plan on having more children... what did you keep for future children and what are you giving away? We purposefully bought gender neutral clothing for the first year so we can save for our next child but I feel like everything is piling up fast... clothes, bouncy chair, play gym, bassinet is being stored at various relative's houses (we live in a small condo) but I feel like it's already so much stuff and she's only 6 months old... so how did you decide what to keep?
