We had three under 4.
It was blooming hard work.
But I can’t say they fought constantly or disrupted that much. They tag teamed it more – always one needing something. The worst bit was the eldest didn’t sleep for more than two hours until he was nearly 4….
Behaviour is the way a child communicates when they don’t have the words. And of course that that age they struggle with self regulation as it’s not a developed skill.
All our holidays were outdoory ones. We treated them like dogs – exercises twice a day. My biggest stress memory was all the kit and clothes and how long it took to faff at times.
So no, I’m not buying the kids are horrid deliberately. And no I’m not calling them rude sweaty things either. They’re just kids.
