I guess the answer to this might be, she's two, it'll pass. My DD isn't so bad with tantrums of the 'shouts/laying on floor/defiant' kind, she's a pretty well behaved and amicable, chatty little thing but my goodness, when we are out she seems to cry so much at the moment .
Tears are guaranteed if there's a toy sharing dispute, if someone has something she would like, if another child gets too close, all sorts of small things...and it works because other mums then tell their children to give her whatever it is she is winging for....her peers seem much more easy going with sharing or having something different (ie a different water cup)
Obviously, if there is a real problem I'm a nice comforting mum honest! But I do wish such small things wouldn't mean the end of the world so quickly!
Any advice?
