Dd is 3 and a half and in the last fortnight or so has started replying to requests and instructions with "no, I'm not going to do that", often sitting down on the spot and crossing her arms too.
I appreciate (hope) this is just a phase but have any lovely MNers got some useful advice on this? I know consistency is key but I actually haven't found anything yet that works to be consistent with.
The naughty step isn't an option as this behaviour is mostly when we need to get out the door, also the reason why I can't just ignore the bad behaviour.
Requests are (I think) reasonable ones e.g: have a try on the toilet, tidy the toys away, put shoes on.
