Well, I don’t really see how you could ensure the items only went to those who need it? And actually, how do you decide who qualifies as “in need”?
OP feels she is more deserving than some people, there are others who might feel the same about her.
Are we going to be asking those requesting these items to provide some sort of evidence as to their level of need? Surely that would be rather demeaning- having to prove your “poor enough” to deserve the free toy, or the worst off of all the people who want it, at least.
I used put stuff up for free but stopped as it was just a huge hassle- constant questions/demanding more photographs etc etc. The level of entitlement, despite the fact it was being given away astounded me. And the replies “mine”, “I’ll take it”- not so much as a please or thank you. I never gave it to those people and would then get rude messages about how they had first dibs/needed it and I was depriving their children or similar sob story. I found the same if you made it a token amount. Then you’d quite often see it posted elsewhere for significantly higher price, which is galling if you’ve given it away/a token amount (even more when you’ve delivered it due to a sob story). And that wasn’t the obviously wealthy mums. So now I either give it to charity shop/recycle centre (some clothes and shoes), or sell it on eBay/fb marketplace.
I also buy second hand- it is more environmentally friendly and saves money. Suggesting second hand is only for the poor is untrue- then it will be criticisms that the wealthy are buying too much, it recycling etc. We need to reuse and recycle more- all of us, not just those on lower incomes.
I think that if you need something specific, post a wanted advert and then you might have more luck.
