Welcome Dano.
Listen & act on every piece of advice you've just been given! As soon as you make it clear to the JW's that you'd rather your children don't go to any more JW meetings, they will freeze you and your children out!
You will very quickly discover that JW's only offer 'friendship' to potential recruits. Their rule is that 'worldly' people are "bad associations." (1 Corinthians 15:33)
