I know you said you dont want him watching tv, but what about if you put on something so the two of you can watch it together whilst you try and settle bub?
When DD2 was born, DD1 instantly gave up her day sleeps. I tried for weeks to get her to stay in her room and nap or have quiet time whilst I tried to settle DD2, and I found nothing that would work.
In the end, the only thing that would give her some time our was to put on a doco or an 'educational' program. But whilst this was on, we were all on the lounge, I would spend the time attempting to settle DD2, and at the same time chat to DD1 about what was going on etc. Some days the doco or program would put her to sleep, but everyday we had some special bonding time. Ok, the tv was involved but it worked. Actually it still works most of the time, and now that neither of the girls sleep, we have fun having some time out learning about random things. At the moment they are into monkeys and penguins, so its monkey and penguin docos airing here!
