Paternity leave ending soon and I'm actually panicking

I've got 2 weeks left of my 8-week paternity leave and I'm dreading going back to work. Not in a 'I don't want to work' way but in a 'how am I supposed to leave this little person' way. My son is 6 months old and we just got into a rhythm. My wife is staying home so I know he's in good hands, which helps mentally, but I hate the idea of missing stuff. Anyone else deal with this? How do you not get bitter about missing your kid's day?
