Weeeelll, let me begin by saying I'm glad you sound great and I hope the rest of the pregnancy is smooth for you.
I love thinking back to the days I had my son, so thanks for the topic and bringing smile to my face.
I stopped working on Friday at 38 weeks and had him the following Monday! Totally unexpected. All my carefully planned activities for the time I was supposed to have off basically went into thin air. I remember texting the friend whom I was supposed to meet for lunch on that very Monday at noon "Lunch off! Beautiful boy born at 10:22." At least I had enough presence of mind to text her
So, my most important piece of advice, based on personal experience is - fill up the freezer. I know this is not nesting as such, no decorating, organising, etc, but this is one piece of work I don't get a chance to do when my nesting kicked in and we have felt it big time. My son was due on the same date my husband's PhD thesis had to be handed in, but the baby was two weeks early, so imagine two absent minded adults, one hormonal and another under the deadline of a lifetime, with no food sorted for the first couple of weeks. Well, except for the baby that is
The other advice - prepare the hospital bag AND explain to the hubby where certain things in the drugstore are, because no matter how many you've bought you'll need more.
My hospital bag was a joke - sometimes around week 30 I threw the basics and leftover crackers (aka "reminders" for the real thing) in thinking that later (later being those virtual two weeks between the last day at work and due date, which never happened) I'd go through it all and replace the packets with the full ones. Well, the baby was early, the bag was as I had left it weeks ago, so a day after the birth and adrenalin levels somewhat down I found myself awake at some crazy hour at the hospital, the hunger kicked in and all I had to snack on were a few old crackers and nothing else for hours.
And, on separate note, if I may add something else - if you plan to breastfeed the baby, I'd recommend to read a lot about it ahead... actually, this point has to do with the food too, now that I read it all again... Get to know the possible problems and issues (mum forums are great for that), so in case you have some issues - and most women do - you know you're not alone and it can all be sorted. Have the numbers of the support groups such as La Leche League or similar at hand in case you need them and don't hesitate to call - they are always happy to help the mums in need.
I've been out of action lately, so I have maybe missed the information - when are you due?
