DS is 18 months, since about two months he's allowed to watch an episode of ITNG before bedtime. As a result every time we are in a shop where they sell anything related to it he gets VERY excited, same with Thomas Tank Engine. So far I have refused to buy anything in order not to fuel this but should I give in and just get him a giant IgglePiggle for Xmas? I mean no other gift would have the same impact but it always went against me to buy this stuff, or should I accept that this is the way forward?
