Night time routine help!!

I'm struggling with a nighttime routine for my 2 month old who will go to bed anytime from 730-830 depending on how much cumulative sleep he's had during the day from naps. My husband and I typically eat diner like 730-8 while I'm breastfeeding him his last feed of the night- something that started during the colicky newborn witching hours but I feel like we need better as he gets older so can you please let me know what you do at what time and even when you eat dinner? I'm guessing we'll have to eat earlier. Thanks in advance and here's a pic of my little pumpkin 😍
