DS has just been constantly whinging for about the last week it is just so annoying, he is usually a happy little boy who plays and laughs loads but in the last week he is whines the whole time, he will crawl along and just whine as he does it, play with his toys and whine at the same time, want to be picked up so I pick him and he whines to be put down, whines and cries all the way through every meal - it is just so tiring and annoying. Is this a phase they go through at this age, any advice on what I can do?
