My kids are getting far too much from me but I don't mind, no one else buys for them.
Santa is bringing them:
DS1 - A Meccano robot.
DS2 - A Lego technic dump truck. Santa was bringing him an el toro loco (monster jam) remote control but DS1 saw it so I am giving him that now instead.
DD - That big pony/unicorn thing that is in all the shops ATM.
