Need I agree with the suggestions up thread of maybe trying not working for 6 months and see how you feel? I guess that as it is your company, if you wanted to go back at any time you could do you so are not really burning your bridges. After a break may feel that you have 'caught up' your energy and miss work. Or you may find you are always busy anyway and feel fulfilled. I never thought I would enjoy not working but I actuallly do most days, though don't ask about this past Monday . Especially as you have the running which takes up a lot of time and involves seeing other people. I have always worked in challenging jobs but TBH, after this enforced career break I feel differently and if I could stay at home I would. I'll have to get a job next year though 
Baby DD seems to be rather highly strung - I am not sure if it is colic (whatever that really is) or whether it is overtiredness but she cries piercingly for several hours most days, usually in the evenings. I think she just fights sleep but it is Very. Tedious. Not helped by the fact that DS screeches a lot so she is frequently woken when she does fall asleep
. Monday was very bad as DD cried for at least 6 hours and DS had a major meltdown over a lost toy piece which went on for a good couple of hours, with general upset for several hours afterwards. And he woke DD up a couple of times. I was in a bad way when DH got home! I have both kids on my own for the next two days, we shall see... I am eating a lot of chocolate these days 
I missed the discussion on hospital bag but it is very fresh in my mind! I took a smallish bag for labout (all my 'cooling' stuff for the heatwave, drinks, snacks, first baby outfit, stuff to read and pass the time) and another one for afterwards which DH swapped from the car (more clothes and nappies for baby, clothes for me to go home in, oodles of maternity pads etc). It worked well as there wasn't much room in the hospital and I moved beds a few times. I also had extra nappies and pads in the car in case I needed a top up or was in for
Much longer than expected. Things I found most useful:
- Bottles of Evian with sports cap - it's hard to drink from a hospital glass if you are not sitting up properly, sports caps or even straws are great for that. Sports cap bottles also be wedged next to you on the bed without spilling.
- A cheap sponge bag from eBay that unfolded with a hook to hang it up from. Meant I didn't have to put it on the wet floor when I showered
- A small turban towel thing for my hair. Hospital provided a towel for a shower (though I stuck one in the car just in case) but I knew there wouldn't be another for my hair!
- Packet of tissues. I got the boots travel pack - like a normal box but in a flexible plastic bag thing so doesn't take up much space
- SNAcks. Hospital food was rank. I took loads of raw cashews and ate them throughout labour. Helped with bowel movements afterwards too
. Chocolate melts at postnatal ward temperatures so best to get visitors to bring that fresh. Oreos were handy for a chocolatey fix whilst not melting.
- A USB power pack to recharge my phone as and when. Was so handy as I didn't have to plug the phone into the wall and then have it out of reach when I wanted it /it rang. Especially as getting out of bed was a bit of a palaver afterwards, particularly if I was holding DD. I use it at home all the time for the same reason, great for recharging phone during feeding /mn marathons
- Flip flops /Crocs. I.e. Footwear you can wear in the shower. As others have recommended
- The thinnest cotton dressing gown I could find. I had a waffle cotton one with DS and even that was too hot on the ward.
Aah, happy days.
