Too many clothes! Help!!

So this is baby number two for me. And let's just say I have an abundance of helping hands. The father isn't the ideal man and has bought maybe 5 items for the baby and his storage. Keep in mind the father is a salary paid employee and I am an hourly less than half of what he makes. Anywho. So because people have seen the lack of help on his part I've been given a stroller, car seat, swing, etc but the most I've gotten is clothes. Which I do NOT mind lol, but only thing is, I now have over 100 outfits of pretty much the same stages "newborn-6 months" I have an overwhelming amount of newborn items and 0-3 months I don't know what to do with it all. Baby boy won't be able to wear not even half of this! I forgot to mention I also found a ton of his brothers old clothing which is the same age range. I don't want to post it on my fb that I want to give them away "due to the people who gave it to me being on there" but I honestly don't know what to do with all this clothes, 99% of it is hand me downs "which I don't mind" and they are pretty much allll new and barely worn, and all washed in baby detergent. I am overwhelmed and don't know what to do with all of this clothes. Please help!
