What are we doing with opened unused bottles?

Asked heal baby care app and sharing in case it helps:

"It's understandable to feel uncertain about what to do with unused bottles, especially since they can hold sentimental value. One option is to donate them to local shelters or organizations that support new parents, as they may appreciate the help. Alternatively, you could consider recycling them if they are made of recyclable materials, but check your local guidelines first. If you're comfortable, you might also offer them to friends or family who are expecting, as some may be open to using gently used items.

Have you thought about any specific organizations or friends who might benefit from them?"

Thank you ! honestly I just saw the container full of bottles. I have them in a sealed container and just want to get rid of them, but don’t want to trash them.

I have given mine away for free on Facebook marketplace
