Monster...i mean mother in law

my MIL just arrived today to see our little one...and I've been in tears ever since. She fusses at me for picking him up "too much"...apparently I'm supposed to let my newborn start screaming bloody murder before I change his diaper or feed him...she fussed because I don't swaddle him...which he hates and screams every time we've done it since he was born. She insisted on feeding him, so I let her, she didn't burp him, just laid him straight down and said he didn't need to be burped, he'd burp on his own...so of course I picked him up and burped him, which was another "lecture"....and have I mentioned my husband has just sat there and let it happen? He's been an amazing dad so far, gets up in the middle of the night to feed him, changes diapers with out batting an eyelash...and this is a man that's never had any experience with babies...now all of a sudden, he's decided to take the back seat. I know how difficult it can be to be caught between you spouse and your parent, but I would never let my mother pull this stuff. I don't know how to make him understand I need him on my side when it comes to our son without seeming like I'm trying to make him choose between me and his mother. I know I have to do what's best for my son, and I will, I just need him to back me up. I'm just so frustrated...
