chocolat and others saying what do the DH do? My dh is a total PITA in so many ways, but he bought himself a near lifetime stock of goodwill when dd was tiny. And boy has he needed it- this is no stealth boast about a mythical wonderful dh, he is a very ordinary bloke and prone to laziness quite often.
Dd was ebf, he dh worked full time, but if she cried in the night he was the one who got up, did her nappy and brought her to me ready to feed, if I was tired he sat up whilst she fed to ensure I didn't drop off holding her, and when done he would wind and settle her.
She was reflux-y high needs baby and he did fair share of shifts walking round the room or taking her out for a midnight walk so I could sleep. We did a strict one hour each when she was really bad.
He always helped clean up any reflux vomit incidents, even if they were on my watch.
As a result there was no task except bf that he couldn't do, and do well. And if I expressed then he would take over a feed of two once she was old enough to take a bottle.
Even now she is school age, he is first up and sorting any night time crisis, be it nightmares, vomit or bed wetting.
We have always had fair shares of lie ins. One weekend day each.
As I said, he isn't some domestic Superdad. He won't Hoover and hates cooking. But we always had equal division of work with the baby. Thank goodness.
