If you're accepting less than 50% custody--why?! Talk to an attorney to fix that pronto.
She took the kids. What day do you get them back? Your parental rights aren't to see/visit your kids they are to have 50% custody of your kids unless you're unfit for some reason.
I hope you do whatever is necessary to be an equal parent in your kids' life. Don't be that nice guy who gets talked into every other weekend and a Wednesday overnight and then regrets it.
