DS is 2.9 and, in the last few weeks, he has transformed from an articulate 'pleaser' to a whingeing (ignore spelling!!) brat
I try ignoring, I try confiscating toys...he just whinges more.
I try to reward good behaviour like when he asks for something nicely or accepts an explanation of what we are doing (that is NOT very often...)
I've even tried whingeing back at him
Help?
