Make a cuppa, eat chocolate, put in earplugs.. Milo has any days like this. I heard that horrible toddlers make lovely teenagers so i console myself with that.
I am trying a reward chart for Milo as time works when I do it, but he does the same naughty thing over and over. So i have a little chart with 4 targets for the day, and if he does well he gets to move up a step on his big chart, and when he gets to the top we go to the zoo. Seems to be helping a little but it's v early days..
