Is this normal. he is generally a happy toddler (I assume) but his constant whinging that this isn't right, that isn't right, the lolly is the wrong colour, the socks are wonky, blah blah blah on and on is driving me up the wall to the point where I want to scream at him to eff off!!!!! (I haven't done so far . It is soooooo trying. I try to avert these instances by second guessing his reactions but often to no avail. WHAT CAN I DO???????
