Hi Adriana,
My step daughter was diagnosed T1 a few weeks ago and returned to start year 1 as normal when term began. The school have been fantastic! Our DN trained 3 TAs and her teacher before she started and we went in to help administer her lunch time insulin for the first week until the staff were confident and could be signed off by DN.
She takes her own snack for playtime so we can monitor what she's eating and I write the carb count for each item in her packed lunch so the TA knows how much insulin to administer (she has insulin after she eats at the moment as she's really fussy and we can't guarantee she'll eat what we inject for).
She's hypos frequently at the moment as she's just entering the honeymoon period and school treat those with confidence. If she feels unwell, they ring. If she hypos more than once in a day, they ring. If her BM doesn't come up after a hypo, they ring! In short, communication is definitely the key.
She's not been offered a statement and doesn't have a TA attached to her all day, but she does have a care plan. Both the school and us agree that she needs to be treated the same as any other pupil with as little fuss about her diabetes as possible. We don't want it to define her.
So far it's working really well and she's a happy, bright little girl
Good luck with your little one and remember, communication seems to be the key
