Just spent the weekend at a family reunion and my parents, sister, DP and her 3 and my brother, his DP and his DS were all staying at the same hotel as us. There was a buffet breakfast in the morning and DS1, being a typical 3 year old, thought he was in heaven and kept going back for more/different stuff etc. He wasn't being particularly naughty - just a bit excitable and giddy.
Anyway, when I got home yesterday, I spoke to my mum and she said 'oh you can tell your sister's 3 are used to staying hotels as they knew how to behave...don't worry your DS1 will learn'.
My sister's DC are 12, 8 and 6 so quite a bit older than my DS1 so firstly, they have obviously stayed in more hotels than my DS1 as they are older, and secondly, yes I probably would expect them to behave better than my DS1.
Not really sure what my mum's point was tbh other than, yet again, making me feel like an inadequate parent
