That's a great letter. (check spelling of intergrated- thought it was integrated?)
E-mail itbut back up with a paper copy as soon as post starts up again, its good for them to have a file copy and it keeps your child at the forefront of their minds.
A meet up would be good- we're just over the Severn bridge so maybe Taunton? (Mum's in bridgwater and FIL in Merriott so would work quite well for me) if that's OK?
