What to do with baby’s stuff after she’s outgrown it?

K

What is everyone doing with their child’s things after they outgrow them? Like clothes, car seats, toys. I really want to save everything because I know we’ll have another one day but that’s 6 years down the road. I know things can happen so that’s a another reason, just in case. But we’re moving soon and I don’t want to drag everything thing with us. I also have a friend who’s pregnant who I could give a lot of stuff too. Why am I so conflicted on what to do?
