You can ABSOLUTELY buy well more than two pieces of baby clothing for $30! Learn to shop at Goodwill and clearance racks.
I think you were stupid to give things that important to someone else to store for you (especially in a trash bag) and you're being overly dramatic. It seems like you just dislike your MIL and found a reason to dislike her even more.

She stored stuff in an unused, unfinished basement. Unless she was storing a dead animal, there was no reason to throw them off. And the MIL went through that stuff and saved the stuff that had sentimental value for her.
Maybe OP should forgive her MIL, after burning the DH's baby blanket in front of her. Because baby clothes are soooo cheap in Goodwill!
