In law rant... And GO!

My inlaws have been driving me crazy since DS was born. They always act like they know better than me when it comes to baby and what he needs/wants. For instance, today at a family gathering I tried to put him down for a nap because he had been awake for several hours and was starting to yawn. I like to get him napping before he gets over tired or else we will all be miserable the rest of the night because he gets so cranky. Instead they decided to pass him around and keep him awake. Well six hours after his last nap he's still awake and starts crying bloody murder. He's only two months old he needs more sleep than that in a six hour period! So again I say he's really tired, but instead they go about it their own way and change his diaper and shove a bottle in his mouth. Then he falls into a dead sleep while he's eating and wastes a bottle (he's on nutramigen it's only good for a short time and can't be heated and it's super exspensive to be wasted). They never listen to me and they are so overbearing that I can't say anything to them. When my MIL and SIL are together it's even worse because it's them against me.

Ok rant over. They are really sweet people I just get so frustrated. Anyone else in this boat? I don't want to feel like I'm the only one dealing with it.
