DH has had a wonderful 5 weeks of paternity leave
and it's hit me with a big kerthump now that he's back at work!
Babe is formula fed, and feeds every 3 hours-ish on demand day and night. We did feed him in shifts so that we would both get about 6 hours without getting up, obviously now DH is back at work that doesn't work...
We need to try different things until we find some kind of a routine, but does anyone have tips for what worked for you? DH is being all 'I'm so busy and important, I can't possibly be sleep-deprived' - cos obviously caring for a tiny human isn't as important as whatever it is he actually does as working! 
I accept that I need to do the majority of feeds, but what would be reasonable?
TIA
