Absolutely do not go, but do as shepherdless said be a great dad and teach them other stuff that will help them make correct (non jw) choices later on.
Going just reinforces the hope that you will come around to it eventually and puts you on the radar for extra attention from the elders etc. It also sends the wrong and conflicting message to your kids.
Looking back, if my non jw dad had made the effort to get closer to me as a kid instead of me just being afraid of him 90% of the time he'd have weakened the very strong bond I had with my ultra JW mother, and who knows maybe i wouldnt have made those dumb choices like getting baptised at 16. If he'd been there for me in those times and i'd respected him and his opinions I likely would have wanted to please him instead of my mother. What a different life I'd have likely had then.
