I'm not sure if this is a developmental thing but I am at a loss at how to deal with it.
Say for example he wants grapes he will say it again and again and again and again until he gets a resolution. If I tell him to stop nagging he then says sorry repeatedly.
It sounds silly but its pushing me and DH to our limits at the moment , not to mention really worrying us that there's something up.
Any advice appreciated. His development is fine in every other way.
