I've got an 18 month old baby. My second so I'm not being pfb.
My inlaws keep patting/slapping his bum quite hard. I really don't like it. They're not hitting him they're being playful but I just want to say "stop".
I know babies bums are cute in their nappies, I get that, it's just they do it quite hard, and often, mil especially and I just don't want people constantly touching his bum unnecessarily.
It makes me cringe. Mil has done it a couple of times to older, school age child although far less often.
I asked dh to gently ask them not to but he hasn't.
