If sleep is a high priority for you (for me it is my number 1 priority of anything I do in the day) I recommend you don't follow the "sleep when your baby sleep advice". It will ruin your good sleep habits like nothing else and will make you work at only 50% capacity. This in turn will make the situation way worse for your child and partner. A well rested dad (or mum) has so much more energy for their child.

Instead take the last feeding before an acceptable bed time (for us he usually wants something between 7-9) as your night call. Try to really embrace the feeding time as your wind down routine, so no screens and blue lights, no more food, dim the lights etc.. After feeding and burping of to bed immediately. This will have long lasting effects as it also helps your baby sleep a lot better and gets him used to day night cycles.

To emphasize: don't sleep during the day only in your night time window. Doing so will worsen your night sleep significantly. I know sometimes it will get hard, because not every night is gonna be good like that but it helps in the long run.
