Sorry in advance for the lack of paragraph breaks... My iPad doesn't recognize them for some reason.
Even though we're only a few weeks in, it's interesting to see how my SO and I parent differently. We're on the same page for the big stuff, but when it comes to littler things, not so much. For example, I think we should keep DD in a quiet, dark area from 10 PM on, so she can get herself organized for sleep. SO thinks its fine to rock her to sleep on the couch while watching TV. 
Tonight we compromised by having her in the living room with him, but with all the lights off and the TV on very low. How do you guys deal with the little disagreements?                
                             
        
Re: Mommy v. Daddy
All that being said, I'm with you on the bedtime thing. Light can affect melatonin, which is what our bodies use to help sleep. If your husband is like mine, I would find an article or something to back up your opinion so he doesn't think you are just being irrational about something silly. Unless it really isn't that big of a deal to you, and then maybe compromise on a bedtime routine that meets both of your needs
Unlike the PPs, I actually end up deferring to my DH on a lot of things. And to this day, he's REALLY good with DD. I've gone away on business trips for as long as a week and he's got things DOWN. He steps up with minimal, if any, guidance from me. And then when he's traveling or working late, I do my system. And that works for me and DD.
My DH and I have slightly different approaches to things and it works. In some instances he was better at some things. He was a master at swaddling back in the day and he does a better job with the bath. It's their special thing. I try to praise as much as I can because I appreciate getting a moment to myself.
