My after-the-birth plan also went out the window. I planned to breastfeed on demand, to do lots of skin-to-skin, for my newborn to sleep in a cot beside me, for visitors to arrive only after day 7 and I also wanted to try reusable nappies.
I've been a mother five months and I'm strangely confident. Maybe it's not so strange. Perhaps I'm hard wired for it. In my extensive experience thus far I have learned how important confidence really is for a new momma.
