Gigi - don't stress to much, homework is reading a reader with them each night - it takes a few minutes, and then some discussion. As for the ages our school has a buddy system where the preps get a grade 5/6 buddy to help them settle in. This has had the effect of really reducing any bullying incidents.
I had a very proud Mummy moment this morning as DD1 attended her first school assembly and got a 'Student of the Week Award' for contributing good ideas. I got all teary - shee looked so little and proud standing up in front of the whole school!
