LOL, you say hubby wasn't pressured to be there. I bet if he decided not to, you would have had something to say about that. What if he went to the cricket for the day and got you to just call him...would you feel the same way? Doubt it.
But I did not get up at all hours when they were crying, mum's job in my eyes. I needed sleep to make sure my job was protected. No job, no money for babies.
I was alone having my babies......their dad went drinking with mates first time around & second time he 'was tired & wanted to go home to sleep'.......i was in labor for an hr & half mind you!
Do i care......nope, i got to share my babies first moments alone with them, & for me, that was the most amazing part.....it isnt often new mothers dont have someone knocking on their door wanting to visit, when all you want to do is sleep & 'be a mum'!
As for 'it being a mothers job' though to be soley responsible for getting up through the night etc......it is different for everyone. With my last child, i didnt stop working, besides the day i gave birth & the following day, so getting up through the night was a shared thing, i worked just as hard to bring money home for our family.
To the OP, i know exactly how your wife would be feeling at this point, i had the same thing happen with my first born, but after just 2hrs, they then hooked me up to the drip to increase & keep the contractions going, my daughter finally made her appearence 10 & a half hrs later. All the best from here, your little man will enter this big scary world in no time! Enjoy every moment, they really do grow way too fast!
