Popped into MIL's yesterday - baby was in snow suit as it was a bit nippy out.
We were only there for 15 mins and baby was asleep so I took his hat and mittens off and undid the suit and left him laying in it, as to remove it totally would have woken him up and we'd have had hell to pay.
Her house is always sweltering as she thinks that babies should be kept with at least 2 layers and a cardigan, and then a blanket, while the central heating is on (we've already had words about her overdressing him, then putting him down to bed with 2 blankets on when the heating is at over 24 degrees)
When I went to put the babies suit on properly, I found he was sweating alot. So I said I wasnt going to put his hat on for the walk to the car so that he could cool down a bit (the car was on the drive perhaps 10 steps from the house, and still warm as we'd only been there for 15 mins)
She looked at me like I had spat at her. 'You ARENT going to put his hat on?! He will get a COLD'
Then in the hall she asked why he had no blanket on either and I said 'Because hes cooling down! He is sweating hot!' FIL put his arm around MIL protectively like I was Satan.
AIBU? Honestly?
