My husband likes to be involved in specific "activities" that are fun--since he is the one that works--he is tired and doesn't have a lot of energy for the mundane--but absolutely does help on the occasion I need it!! But you need to schedule that time into his week--I wouldn't even worry on a daily basis right now. One time per week like Saturday at 2 PM he takes the twins to the park. Then Sunday afternoon he takes your teenager and they go to a local water area and do kayaking or canoeing, or if they're sports oriented to the driving range (we do this even with my 7-year-old)--or take everyone to the zoo. The orangutangs and gorillas are always a hit. (With the teenager especially--you want to avoid going to movies b/c you want time to interact and talk.) Or they could go walk around the mall together for a couple of hours. I'd start with 1x/week--nothing changes in a day! :) Good luck to you guys!!
