I think being sent home so early isn't always a help with breastfeeding...from DM's description of having my brother in the late 70's, they were kept in for 10 days post partum and their only responsibility was to look after themselves and their baby, short and strict visiting times so they had the time and space to learn to be a mum.
I stayed in overnight with DS, but as soon as I got home I felt a bit inundated with visitors and felt like I needed to "get back to normal" as soon as possible and be washing up and washing clothes etc. just so I felt in control.
I've told DH not to commit to any visitors until after I've had the baby so we can see how the birth goes and how I'm feeling. I don't mind having his family visit a day or two after we get home because I think it would be a bit rude not to, but I will ask DH to ask them to keep the visit short eg 1-1.5 hours ish!
I also said to DH I would like to lie in bed this time instead of lying on the settee and suggested that DS could come in and snuggle up to me and we can read books together.
I don't think I had pnd last time but I think I could quite easily have gone that way. I found the birth amazing and then felt like I'd been hit by a car by the time I was back home! At least this time I'm prepared and I know how to "air" my stitches and I have a cot top changer this time to help with my back 
Now I'm on maternity leave thank goodness as I'm so tired! At some point I need DH to pile the birthday and Christmas presents on top of our wardrobe and also to put the pram back together. I just need to have a big spring clean. Everything is as tidy as it's going to be now!
