When I see my mum, she'll make comments, usually about my DC and then will say not to tell my DP because 'they'll only go on'.
So the other week we went to a party and dc had some lovely dungarees on. She's only 7 months. They were really nice, but comfy. When I saw my mum a few days later she said 'why wasn't she in a dress? I never see her in a dress! Don't tell your DP I've said that'. She'll whisper this as DP will be on the way in from the car.
Then yesterday we went for a meal and DP went to the car to get something. My mum then said 'why isn't DC playing with the toy I got her? I never see her with the things I get her. Where's the toys I got her?'. (My mum has probably bought her 2 small toys which dc does play with).
I said to my mum that I was rushing out of the house and just grabbed whatever was available.
Then mum says 'don't be telling your DP what I've said because they'll only go on'.
So I said to my mum 'maybe you shouldn't keep saying things to me that you want me to hide from DP because you clearly know it isn't ok'.
I don't know if I'm being unreasonable but it does irritate me that she does this. It's almost every time I see her now.
