I don't think he's ready either but if you want to pursue it, they should be more proactive about it.
At daycare, my eldest was forced to sit on the potty and she got really stubborn and refused to train. I knew she wasn't ready, but they wanted to pursue it. She didn't train then and was still in nappies until 3, but got it straight away just after turning 3. My son trained at 26 months as he refused to wear a nappy and has been tt ever since.
