i think by all means your children should come see you that is if they want to.two of them are older enough to be ask & the 3 yr.old is not old enough where i can see it makes any real difference. as many time as my son has been away his would not know him if they had not have gone.he is close to all his children.i think it is important for children to know there parents no matter how good or bad they are.they grow up setting their own opinions of them & it is not hear say.it is tough on kids to have to leave them but it is tough on adults also.saying a prayer fpr you & your family.
