Hi,
Well like many have said, it is really down to how you think you are going. Is there any chance that you can not confirm someone to stay, but if you need them, you can call and get them over asap?
I know with my experience I needed my mum. I was discharged too early. (The hospital reckoned that needed the bed) I had an infection, and James couldn't feed. I was expressing then syringe feeding for the first week of his life. I was in tears daily and was exhausted, as expressing then syringing every 2 hours was exhausting. (He also wouldnt take bottle or boob)
My DH was then in a motorbike accident and broke his neck. He spent 3 months in a brace, and couldn't do anything. So mum didnt actually stay with us, but was basically here every day. Doing things like walking the dog, cooking meals, running the vac etc.
I actually ended up with Post natal depression, and spent a little bit of time in a mother/baby unit in hospital, and without support I dont think I would have managed at all.
The thing is to ask for help if you are at all in doubt. But if you don't need it don't feel that you have to accept it, just because it if offered.
