With regards to sport, my deferred child was given the option of either playing football with the cohort he “should” be in (I.e the year above), or his adopted cohort.
He chose to play with the year above and the difference in his physical stature, core strength and competitive nature are very evident to see. It’s also very obvious during the training sessions that he is a year younger than some of the other boys just by his maturity levels and his inability to sit and listen, and focus in the same way they are.
When he started school in reception, although he was the oldest in class he was still one of the smallest.
He’s in Year 3 now (‘should’ be in year 4) and he’s still one of the smallest in the class.
Although he’s the oldest in the class, there are 6 other children who turn the same age as him within 7 weeks of his birthday.
There is this idea out there that deferred children are so much bigger than the rest of the class, and 14 months older than the rest of the rest of the class, but in reality, they are no different to the September, October and November born children.
My son’s best friend is an early September baby, his friend’s birthday is only 5 days after my my son’s, so I’m not sure my son being the eldest in the class by six days puts him at any huge advantage.
One thing I have noticed though is that my son is in a friendship group of 6 children and coincidentally they are all Sept-Dec birthdays, so I do wonder if naturally children do just veer towards other children that are at the same emotional/maturity stage as each other. Like I said, could just be a complete coincidence though.
