I would say 100% go if you have a volunteer to stay with him while you are gone. You and your children deserve the break and to live your lives. He obviously wants you to go enjoy time with the kids and your family also. Me and mom have been lucky in that we have been able to ocasionally get away for a day or two here and there although it took a lot of coaksing to get her to go the first time. You also need to look at it from the perspective that you better go while you can. As things progress the ability to do those kind of things greatly deminishes. I hope you and your children go and have a great time and take lots of pictures to share with him when you return.
