Hello and welcome I hope I can be of some help. I've worked in reception for the last 2 years but I've not read many books on the subject except the Foundation Stage Profile (our Bible) and the Jolly Phonics books. I've found courses of much more help. I have 3 one day courses for TAs and these gave me a big insight on how to work with the teacher and tips and hints to help eg don't sit at the back of the class during carpet time as a child has to turn to look when you speak to them and this distracts more, sit at the front to the side of the teacher and you have eye contact and a look says a thousands words. ( make sure you practice the 'look'

)
I would volunteer to attend any course that you are offered.
