I know there's a similar thread on discussions of the day but didn't want to hijack.
DS is almost 20 months old and in the last few days has become very...challenging. Whatever I ask him to do gets a 'no' in return with a massive sobbing tantrum if I push the matter where the only way to calm him down is to cuddle him. His nursery said he responds well to stickers which i'm using but they don't work very often. I know its a normal stage of development - he's testing the boundaries but what could I try in terms of discipline? Once he's calm should I keep trying to get him to do what i've asked? It's only small things like helping me put his toys away which he used to do no problem.
