I have non identical 6 year old girls who are in Year 1. DT2 is very studious, loves reading and writing, has a great thirst for knowledge and we have just been told that academically she is equivalent to an end of year 2 child. Not sure how they "assess" this though .
DT1 has very little interest in reading or writing or anything involving sitting still. Much more physical, very sporty and still struggling with reception level school books.
Now this has never bothered me before really, they're both happy, they both like school, they're just different. But this weekend DT2 has been gloating about how well she is doing and how much extra homework she has been given, and how she could read DT1's book last year etc etc. I've obviously talked to her and explained how unkind and unnecessary this type of behaviour is. DT1 is upset by it and feels as though she is is slow or stupid, despite my attempts to make her feel better.
I'd be interested in other twin mums' experience.
