Hi Crescendo, hugs to you, take a deep breath and relax. As suga says once you are on your own you just get on with it and manage. The key is to get a routine which suits you and the babies from early on.
I was very poorly after having my twins and spent 10 days in hospital, the babies were released with my
DH at 4 days old, bless him he was fantastic on his own all night at home then brought them to the hospital to spend the day with me all day.
I had help every day for 8 weeks but this was due to me being so ill as i was not allowed to lift anything, not even a bag of sugar, but from 8 weeks i just got on with it. We have a good routine and stick to it, even if we leave them with family they adhere to it and everyone is happy. My Sil has a single baby 6 weeks older than mine and my Mil hates looking after him as he has no routine, and he will just fall asleep at night with no warning due to this then they complain as he wakes in the night hungry!!!
Good luck to you and cherish every minute, they grow so fast.
