Can you please clarify? Are you saying that because you want <B><I>more</B></I> than <b>all week plus alternate weekends</b>, that your children's father shouldn't be allowed to continue with the court ordered visitation that is established to allow him to see his children every other weekend?
That amounts to you having approximately 70 summer days with your children, to his 20 (give or take) and that certainly seems like "extended summer parenting time". Does your divorce decree state that he must forfeit all his summer time with the children to you, if it is your desire? Depending upon the wording of your visitation agreement, even if he had taken the 30 days of summer vacation, which offered to him because you <i>already have</i> extended parenting time with the children by having them all week, he most likely would have been able to have his alternate weekends during the remainder of the summer. Good Luck!
