Congratulations on your baby!
I really feel for you because was in your exact situation a week ago, although mine started off as a home birth. Things went considerably off piste and I ended up with an episotomy and forceps delivery in hospital as well as 1500ml blood loss.
It's full on! And just as you're coming to terms with it all you have a tiny demanding baby and no sleep! I had to work very hard the first few days to stay steady, I think the hardest feeling was a sense that I was going to be like this forever- sore and a bit shellshocked and not able to even sit up.
A week later, I've totally turned a corner. I'm still a bit sore but having big gaps between painkillers and I've been up and about. I think the only thing you can do is take it steady. You have to let your partner pick up the slack and work on being kind to yourself about that. You need time to heal and rest, especially with the blood loss and low iron.
It took me a few days to try having a bath because I was convinced it would be painful and I was scared, but it was amazing. I put some drops of lavender in milk (to dissolve the oils) then added it, it was heavenly. I've had a bath every night since, I give the baby a big feed then DP cuddles him and I get a clear half hour. Also DP would run the bath for me at first. I would also use the showerhead rather than loo roll after using the toilet at first because everything was so tender, I got good at having a quick lower body shower.
I've been cosleeping and breastfeeding lying down which might not be your plan but has worked really well for me. But that first week I couldn't lift the baby to move him from side to side so I would wake up DP to get him to do that. Also he did all nappies for the first week.
We got takeaways about half the time in the first week as well, I had luckily managed to get some stuff frozen before giving birth but it was nice to have no effort meals too. Friends who offered to help got made the most of too- I got a friend to pick up extra pads and painkillers and bring them round rather than have DP leave me.
I really hope you can be kind to yourself and let yourself be looked after a little bit. Things will get easier, once you're able to get around a bit more there's loads you'll be able to do with the baby. Until then, look after yourself and hang in there xxx
