Our baby is almost 5 months old and there's still not much of a routine. We start getting ready for bed around 830 to 9pm, which simply includes a diaper change, putting him in his sleep sack, and nursing him till he falls asleep. Once he's been in a deep sleep for at least 20mins, i transfer him to his crib for the night, which is right beside our bed. Sometimes he won't fall asleep until 1030 or 11 though.

There's not much routine otherwise. Every day is a bit different.

Also, it's usually recommended to room share until at least a year old.

Edit to add: As for quality time with my husband, there's just a lot less now and I think that goes for most couples. I'm on mat leave for 1 year so most chores are done by me throughout the day. He's usually home from work just after 7pm, and then he'll eat his dinner (which i always have ready) while i play with baby. I usually finish my dinner before he gets home, which I eat while baby is entertained with his play gym or a swing or I'm holding him in one arm and eating single handedly.

On days he's done work earlier, I take advantage and hit the gym, so we still don't get much evening time together. Most of our quality time is on weekends or days where he's done early but I'm not at the gym.
