I went there two years ago. You can usually get free tickets posted to you if you have been there before and have registered yourself there.
The Pregnancy, Babies and Children's Expo is actually very good. Not that it provides lots of useful info for new parents or parents to-be, but it was populated by merchants who try to sell you stuffs, some at very good discounted price. For example you can source cheap baby wipe or nappies there.
