Mt 2yr old (just i.e 24 months) is a great talker & learned the word 'sorry' months ago (although not in context), so when he leapt on my from a height yesterday and hurt me, I thought now was the time to ask for an apology. 15 mins of 'please say sorry to mummy. When you hurt someone, you say sorry' on repeat, lots of furious wriggling and some tears later, I got my 'sorry mummy'. DH thought I was being unduly tough to insist. When did your DCs learn about saying sorry? Is two plenty old enough and I should persist?
