Spend loads of quality time with your partner - conversations not about poo or sleep are good. Have lots of sex.
Go out ALL THE TIME - the aim is to go out so much that you just fancy some time at home for a few months.
Don't watch any telly, that's all you'll be doing in the first few months.
Long baths holding real books with two hands.
I'm torn between suggesting you practice eating with one hand, or enjoy eating with both a knife AND fork.. maybe split your time over these two activities. Particularly focus on eating things like roast dinners or spag bol with one hand - plate or bowl must be balancing on the sofa arm, not being held sensibly in the other hand.
Don't worry about lie-ins too much - you can have those with a baby. We all got up yesterday at 2pm.
Run, swim.. exercise at leisure rather than on a strict time limit like you will be doing afterwards.
Spend some time looking (and trying on) breastfeeding tops or dresses - I've had to do online shopping for mine, and it's a total pain to get them sent back. Not to mention the impact on my cash flow. Make sure you have clothes sorted out for immediately post birth - those first few days are hectic, you just want to be able to wear comfy things that enable easy boob access, and you don't really have time to dither over the wardrobe every day. Maybe this is obvious? I know that I felt really unattractive those first few days, and not having things to wear was part of it. In fact, it's only now at 2 months that I feel OK in my clothes - I've sorted out underwired nursing bras, have sorted out tops that work... so I've stopped wearing my maternity sacks finally.
Just enjoy time alone. I didn't get even an hour to myself until 6 weeks post birth, and then I didn't enjoy it all that much because I was feeling odd about not having her with me!
Oh, have conversations with your partner about expectations - it's hard to do properly without resentment when you are sleep deprived and hormonal. Try this one: yes this baby is now your full time job, it's also using all your social time, hobby time, alone time and a lot of your sleep time - when he is home from work, you should be finished with 'work' too - the rest of the time is about shared parenthood, not him 'helping' you out. Ie, if you are feeding the child, he needs to be doing stuff that helps the household/you first, before he plays on his phone - that's what you'll be doing when he's occupying the child. There are a lot of things to resent in the early days because it is completely skewed towards you doing all the work, you need to try and prevent some of that resentment building up by making sure he's clear about the expectations. But that might just be us!!
Get things like portions of soup and stew in the freezer ready for a microwave - if you imagine they need to be eaten one handed it might help later on. If you don't cook, then M&S do good 'mini meals' that are ace for lunches and freeze OK.
Type two handed!! My baby is currently in a sling but it's still hard to type two handed around her.
