The CHKD here told me they threw away an entire dumpster full of baby/children's clothes because of the new law affecting children's products. She was really sick about it because so many people are struggling right now as it is. This is happening all across the country to items for children ages 12 and under.
According to the CPSC, they do not have to throw them away, but: "Those resellers that do sell products in violation of the new limits could face civil and/or criminal penalties." so it is likely most thrift stores will.
eBay is still allowing the sale of them there, but says they are watching the issue carefully and will make changes as needed.
I suggest you give those items to someone you know or FREECYCLE them. If you give them to the thrift stores, they will go unused and become a burden to our landfills.
