Really good that you asked. It never occurred to me to wonder - I think, like many, that I assumed that I would be looked after! I would have been much better prepared if I hadn't assumed that.
Like many here, got some skin to skin time, birthed the placenta, vit K injection, a shower, and a cup of tea/toast. Baby napped whilst we waited in the delivery suite for our notes to be printed out to take up to the ward. This took a long time (second time it took longer for the notes to print than it had taken me to give birth! Fast labour, slow printer!) so we took some photos and hung around a bit.
Then the hard work started. I had laboured through two nights, so after 48 hours with no sleep I was knackered, but no, no naps. I battled to breastfeed as baby couldn't latch, and tried to snooze, but was on a very noisy ward. I battled to do anything and to stay clean as I was bleeding a lot, so standing to change baby, or walking to get food was difficult.
I had to stay in for five days as my blood pressure crashed, and found the stay in hospital a lot more difficult than the birth itself as I felt so badly prepared. I also struggled to work out how to visit the loo or shower, since we weren't allowed to leave baby alone, but the babybeds wouldn't fit into the loo. I took my sling in second time.
First time I was eventually encouraged to take baby into bed with me by a nice nurse, for snuggles. Second time, I was home the next day, I was well and baby was much happier than his older brother and the hospital had banned babies from in-bed snuggles by then.
So, yes, be prepared to push through with little sleep - if you do sleep well, then that is a bonus. Be prepared to do everything for yourself and your baby. Then if someone helps, again - bonus! The only thing that the midwives on the ward did for me was take my blood pressure and check on the state of my bowels! And of course, they tended to arrive to do the bloodpressure whenever I fell asleep!!
