Since I was a week old I was taken to long Latin masses with my sisters .Carrying on wasn't an option and we learned to sit and stand and kneel when everyone else did .It was not something that was remarkable ,it was just how we were raised.
My eldest two GC were raised RC and they had a similar upbringing ,often taken to church by their other granny when their Dad was working .Apart from the odd child taken out if upset I genuinely dont remember sitting for around an hour ,sometimes more ,being an ordeal .
When those two GC were 6 and 3 we took them to a christening in a church where children are normally left in Sunday school.I wasn't happy about handing them over to strangers so kept them with me ,despite the disapproving looks from some of the congregation .
They were impeccably behaved ,apart from my GD not knowing any of the hymns and singing Twinke Twinkle little star to every one...and there were a fair few .
We were congratulated on their behaviour by numerous folk as we left after the 75 minute service .
Someone earlier said children of that age CANT sit for more than 15 minutes ,in my experience thats not the case ,its how you train them that counts.
I could take mine anywhere and they didn't act out and no they were never smacked.Iwould never have let any child cover my mouth or be cheeky in public ,maybe his nanny isn't doing her job
