Both times they were the best weeks of my life.
I had planned sections for them both and my recovery was great both times.
First
2 nights in hospital. Got back and had visitors within an hour (my choice). I went out every day, mostly visiting cafes and eating a lot of cake. We shared night feeds equally so I wasn't particularly tired. I slept far worse in pregnancy so it was nice to rest up a bit.
3 weeks in I hosted a party for about 30 people and did a lot of baking. I was going out and about to places like the zoo by this stage. As I was bottle feeding, I was able to do things like using a night out with friends etc.
Second
Obviously was different as we had a toddler as well. Within the first week we'd been out to a couple of cafes, a restaurant, shopping, a day trip to see friends and had friends over for a bbq.
I was going up and down slides at soft play within about 2 weeks.
Baby was far less settled than my first, and she refused a bottle from birth, so she ended up being exclusively breastfed, but that worked fine. She was colicky in the evening, but a walk in the sling helped, as did bouncing on a ball. From about 6-11pm each night she would either be crying or on the boobs, so I played a lot on my phone (she found the tv a distraction). She wasn't a good sleeper so I was knackered, but a lot less than I'd be later on.
We went on holiday abroad at 6w, as I figured an evening walk on the beach was far nicer than home. We had a great time - the toddler was much harder than the baby.
I personally found newborn the easiest time by far. I've found my children got harder (and night sleep deteriorated!) as they became toddlers.
I'm lucky though in that I didn't get any baby blues. I felt hormonally charged and emotional, but only felt happy emotions. I felt like I could take on the world. I didn't find it overwhelming or stressful, it was like I'd found what I was meant to do in life. My happy place was having a newborn.
If I could repeat postpartum for the rest of my life I'd be a very happy woman.
