You didn't mention it...There's the middle ground, as well. Half day daycare/preschool. From say, 9-1. That would give your hubby time to do breakfast/morning routine, several hours off to recharge/get things done (and your son several hours of active play), and both of them time together in the afternoon. You could even start off with just 3 days (in a row is usually best), and if the two of them are thriving, bump it up to 4 or 5 days after several months.
We did something similar, and it was spectacular for both of us. It's the rare parent who's not a BETTER parent with a couple of hours a day "to themselves", to pursue their own life/interests (or even just be able to have conversations with complete sentences on a regular basis).
Also...just a note: Your hubby may not actually be watching as much TV as you think. (of course, he may, i certainly don't know him;) For years, our "downtime" unfortunately coincided with the times that my husband came home from work. Not matter how run ragged we were by the day, my hubby never quite believed that we hadn't spent all day doing exactly whatever we were doing when he walked in the door. In a book my grandmother gave me (printed in 1906) "Tips for Young Housewives", one of the things that gets mentioned is just that...to "appear" busy when your husband comes home, because whatever they see is what they'll believe you've been doing all day. I didn't put any stock in that until after I went back to work and my husband asked if it was nice to be busy again, and I remember looking at him feeling rather shocked. Busy? All I had to do was manage 4 docs, 9 counselors/social workers, patient liaising, the phone, and paperwork. It was out and out relaxing. To this day I don't think he understands a 15hour shift taking care of a child & a house...and that it in nearly no way resembled our weekends home with him.
<Grinning> I'm not trying to say you're the same way, and I think it's FANTASTIC that you're looking for ways to give your wee one and hubby a break! :)
Good Luck!!
