My DS is 2.9 and I find it hard to determine what is his own personality and what is just the behaviour of a 2 year old.
He is wilful, utterly determined and will not be told about anything, he always knows better. He is bossy and demanding and throws spectacular tantrums if he doesn't get his own way. Some days are a real battle and I am terrified by the prospect of these traits existing into teenage years.
So, did your toddler keep much the same character as they grew up or did they change significantly?
