Child Custody

My question involves a child custody case from the State of: missouri
Ok I have two seperate issues I need addressed.
1. I have joint custody of my children, but live out of thier state. For my regular monthly visits, I drive down to see them (two weekends a month) as per our agreement. This summer I would like to take them to where I live, my ex says no, because the papers say visitation is to be in thier state HOWEVER, there is a paragraph that states: either parent can VACATION with the children out of state... so since I get three weeks in the summer with them wouldnt that be considered my vacation with them thus allowing me to take them out of state?

2. I just had my visitation with my kids this past weekend. My son got sick and was vomiting, I called my ex immediately and let him know what was going on because we are SUPPOSED TO (even though he never alerts me to anything we are supposed to alert eachother to). My son asked to stay with me an extra night, he just wanted to be babied. I called my ex and of course he said no. Then he told me that my son is only ever sick when I visit (I dont remember him being sick on any of my visits and as I stay with my mom during the visits I have a witness that can attest to that) and threatened to stop my visits. The last time my son was sick they took him to the doctor, and it was well over a week and a half since I had seen him, couldnt have had anything to do with me, and thats the only time I can even recall him being sick all year. I am afraid he is going to try and keep them from me, are there any tests that can be run on him to prove I had nothing to do with whatever virus or bug he had? I am so upset that he'd even say that to me, is there any way to prove it untrue? Is there anyone I should report his threat to? My son said he didnt throw up at all since last night, so hes obviously over it but if theres any way to prove it had nothing to do with me I want it documented and the threat he made, what can I do?

Thanks for any help you can provide! :(

If you are talking about where you exercise your vacation time, and the order says you can exercise your vacation time out of state, then you can exercise your vacation time out of state. It sounds like you may want to revisit the court order to eliminate the provision that all visitation occur in the state where your ex- lives - what's the purpose of that language?

Kids get sick. There's no way to prove after-the-fact how they caught what they caught. Usually it's from another kid, usually at school or daycare.
