Hi ger_mum,
Thanks for your reply. Now I have to reconsider whether to send my boy to playgroup when he reached 18months. Cos last sunday, we went for a trial at Baby Jumper gym. He cannot concentrated to look at the flash cards, even went up to the teacher and snatch her cards when she was flashing. For the whole lesson, he was running about and I having a hard time making him sit down. I think will have to wait til he is older and learn to sit down quietly when he is told, then can send him to classes.
