good questions Kirsten, one is 7 and one is 5,they have both returned from a beach holiday which is when I really noticed the change as I was spending a lot of time with them, they are both at school, the 7 year old was accelerated last year and if I look at it closely I would say the change in him is more dramatic. My 5 year old is in pre-primary doing year 1 work and it probably a little more eager to perfect her work outside school hours (she is the perfectionist). At the moment they both seem happy but full of beans and so preoccupied amongst themselves that parental input is being ignored (not heard????) they are behaving a little silly at the moment. Hope this bit of input helps.
