My DD is 15 months old and I have to admit, she's always been an angel.. always laughing,playing with you,babbling, and she's so sociable with everyone,but... just recently, if she doesn't get EXACTLY what she wants, when she wants, she has a crying fit which is SO unlike her. If we're out walking and she's getting close to danger, near water, for example, and we stear her away, she can be un-controllable.. Is this just normal toddler behaviour or do we need training in discipline??
