hiya,
theres a great softplay area in Glengormley beside the Sportsbowl and Mc Donald's called FunWorks. I've taken my son there quite a few times and you can go on the frames with them, its great fun and well worth the money! They also have a mother and toddler group tho i'm not sure how much it is. I've also heard of one in Broughshane outside Ballymena called Monkey Business, tho i've yet to try that one. I'm also a fan of Cheeky Monkeys in Ballyclare, been there loads too :)
