My yr 1 aged 6 1/2 DS has turned from a sweet placid gentle little boy to a complete and utter cheeky, rude, stroppy, angry, tearful little sod in the last week. He doesn't do heat v well and is struggling to sleep my before 10pm despite keeping all routines the same. Is it just my child? Is there something wrong or does he just need the holidays sooner rather than later?!
