I don't mean to pry, but it seems like you are on the short end of the stick when it comes to having your children. Could just be my perception. Do you feel you are getting a 50/50 split. I am assuming you want this. Also I have read where bouncing the children around can be diffciult on them. That is one reason why we went with the alternating weeks with visits (i..e my W would come over to my house during the week to visit when it was my week) or planned joint activities during the week.
The way I view it, your home should be just as much a home for them as your W's. I know in my sitch it seemed like my W viewed it as her home was home and my place was da-da's home. That is one reason why I spent a good bit of effort in making my house pretty much all about the kids. It was interesting when we were all in the van (W included) and my daughter out fo the blue just says "no...I don't like mama's home, I want dadas home". I of course corrected her and told her it wasn't nice and that she had two homes.....but that didn't keep my W from puttingher sunglasses on.
It just seems to me that your W is arranging the custody such that it suits her tolerance to absense from them and perhaps doesn't give you the same courtesy. Maybe see how things go with this weekend.
