I read a thread about tantrums a while ago. Ds has started having tantrums that would make your average diva envious!!
Yesterday while in mid flow, I caught his eye and said 'don't laugh', he started to giggle but that was quickly replaced by the tantrum, I kept it up, saying don't laugh and stop smiling, and he kept laughing and trying to cry at the same time, eventually gave up and the tantrum soon ended!
It worked twice this morning to varying degrees, but it does seem to make them shorter.
So thank you, I wish I could remember who suggested it in the first place to make it personal.
