Laura,
We have been to the baby show nearly every year and loved it everytime
Whilst having not (as yet) attended as an exhibitor - just to experience that sort of exhibition was awesome
Whilst there were naturally many many 'big hitter's giving away what seemed the world for free, there were more than plenty of SME's also in attendance
I would say that a good 30 / 40% of the stands were small businesses...some doing nothing more than getting their face seen by the public
I have attached a link here to the show at the NEC

Hope it is of some help
