By DC3, I had my routine pretty much set it goes something like this:
First 24/48 hours:
Sleep when the baby has been fed, regardless of if he or she is asleep or not!
Everything else can be dealt with by DH. He is in charge of feeding me, looking after the other children and I am left in my bed unless I feel like venturing downstairs. People are welcome to visit, but I am not expected to appear as if by magic looking radiant and ready to regale every detail of the birth.
Plenty of time for that later,when I have recovered.
I usually welcome the time to 'come down' from the birth, cry without having to explain to worried children why mummy is sobbing for apparently no reason!
Throughout the day the children come in for snuggles and to watch TV, bath/shower and into clean PJ's I do not get dressed until at least day 3!
My DH only takes about a week of for paternity leave so I make sure I rest as much as possible, by the 3rd day I am usually ready for getting dressed and going out for a walk.
Days 4/5/6/7 and beyond!:
Establishing a routine of sorts that only has to include everyone being clean/fed/dressed, if beds don't get made or the hoovering doesn't get done tough it wont last forever and those early days fly by so quickly!
My tips for the early days would be, baby does not need dressing in anything more complex than baby grows, cute outfits can come later!
Invest in some disposable/good quality paper plates to eat off that can be binned rather than pots piling up in the sink! (unless you have a dishwasher of course!)
Leave out Tea/Coffee/Sugar milk,mugs etc, and tell visitors to help themselves.
Be realistic, you DO NOT have to be dressed to welcome visitors, they are coming to share your celebrations and will be reminded that you are recovering, its surprising how much getting dressed/hair/makeup etc takes it out of you.
Likewise your house does not have to be tidy, wasting energy trying to maintain your usual routine when you should be resting will only exhaust you, you have forever to perfect being supermum, the days after such a massive event, trust me is not the time. The world will not stop turning if the floor isn't mopped!
You need to consider it as a Babymoon, and enjoy it, as it will pass in a haze, take photos,lots of photos enjoy each other and remember that there will be frustrating moments for you all but these will be eclipsed by the overwhelming love you will all share, and that is what is important, nothing else really matters!
(I speak as someone who fell into the 'supermum' trap 1st time around and ended up a gibbering/exhausted wreck!)
