I make it up in other ways. Sign up DS for a camp he likes for a week (knowing his dad won't come pick him up all summer), take him for day trips to amusement parks and stuff that I really can't afford, but I feel guilty knowing he's not getting time with his dad. I at least want him to have fun memories of his childhood. It's very hard. I don't want to spoil him, but I also don't want him to feel like he's any less special, or less deserving since he doesn't have a dad around.
