DS1 is 22mths, and the last few days has been very difficult. Bitten his brother (almost 6mths) quite nastily, kicking him on the sly, throwing DVDs and toys etc.
We were putting him to sit in the armchair, telling him no, then asking him to say sorry. (He can't say it, but he smoothes the person's head instead) But he now finds this funny, and marches to the chair before we say anything, laughing at us
We are praising the good, but it's hard to just ignore the bad when he's hurting someone or breaking something...
What to do?
