My question involves a child custody case from the State of: texas

Me and my ex came up with a simple agreement of every other weekend. The court order does not state if a holiday I can not have mykids. There have been two visits that the mom has taken away without working out some type of make up days etc. I was letting the contempts build up but also think after I file contempt, i will file for a standard visitation. I want black and white and i feel the court order that has been in place a little overa year is not clear enough. My question is

if my weekend landed on thanksgiving weekend and it is not mentioned in the court order whatsoever, is this a valid contempt? Also, does anyone think going in for the standard visitation is better?
