My son's just started reception and is finding it really hard. Several different teachers, heavyhanded discipline and rewards, noisy lunchtime, dull play stuff, seem to be the main problems. He is having night terrors for the first time. I have talked a bit to the teachers but suspect it is mostly the huge leap into large class size- he is used to nursery. Is all of this fairly normal, and how long should I leave it before considering if something is really wrong? It's not a great school but it's our local and we have no other options.
