Hi Nic, I know you may be keen to get out of there as soon as possible, but I would suggest that you wait until your milk has come in and make sure that bubs is attaching OK. If you go home on Wednesday, your milk probably won't be through, and it is much easier to see the Lactation Consultant when you are in hospital. Also the day 3 blues will be kicking in about Wed/Thurs and it is nice to have someone there to take the baby or to just hand you a tissue!
Also the catheter thing, they like to leave it in overnight and you are still pretty numb from the waist down until the next day. I had my last baby on the Monday afternoon and the catheter stayed 'til Tuesday when they got me out of bed. The drains however stayed until Thursday.

Where are you having your baby and who is your Ob?
