Yes. And he had taken them shopping for a card and a small gift.
From the start, our focus was to do our best to keep our issues to us and not involve the kids. It was very important to me that THEY have something for him on holidays and his birthday. He does the same.
As for fathers day, I take them shopping for a card and gift to give to him (their choice always). Then, when they're with him, I treat myself to a Father's Day gift. (Afterall, I'm playing both roles now.) Usually a trip to the hardware store for a 'guy' gift (usually something for yardwork). :)
