ds (2.7) has been at his nursery for 18 months. he is shy and most of his friends are a few months older than him. this morning we arrived and found he'd been moved to the preschool class (with his friends). I totally understand wanting to keep him with his friends, but is he a bit young to be in a class of 16 children, officially 3-5 years, with just 2 adults, or does it not really matter as long as he's happy (which he says he is)?
am aware I am a bit paranoid of change right now, as we have twins due in a few weeks, and I was expecting the move to preschool to be in January, so not coinciding with their arrival.
