Is it safe to leave your children at the active fun play area? Specifically at Megamall?

If your child is still a toddler, I would advise that you still accompany him/her. We've been there several times and I always accompany my child inside the play house. I noticed that there are a lot of bigger kids who might accidentally push or hurt smaller kids, so it would still be better if you keep them safe at all times. For bigger kids, I guess it's okay for parents/guardians to stay out of the play area but still be cautious of what activities they do.
