Sleepyhead - no. Safest for baby is alone on its back flat sleeping surface in own empty cot.
Breast pump. This is the only thing that if you need it, you might need it right now. If funds are not incredibly tight, I'd buy a cheap/manual one as a just in case. I speak as someone whose babies initially latched well and then both times, on my first night at home, refused to latch and my engorged breasts were desperate to see a pump for relief and to maintain supply until we could get BF help the next day. If you need a pump at 9pm and all the shops are closed, it's a long wait until the next morning.
Similarly, I always say it is responsible parenting to have a )small) quantity of formula, some bottles and the means to sterilise them in your house, even if intending to breastfeed. Anything could happen that could prevent breastfeeding taking place in the early days (I got readmitted urgently to an acute hospital in the early days and it wasn't safe for my baby to accompany me on the ward) so you will be utterly thankful for knowing your baby has a safe alternative right to hand if needed. People will tell you the mere presence of formula will prevent you breastfeeding - I believe that is nonsense and it is responsible to e sure your baby has an alternative food source for unforeseen events.
perfect Prep is not I believe proven safe. Please don't though use the method described above either. Fill exactly the instructions on the formula can. For normal formula, you can then flash-cool it really quickly and store in the back of the fridge for up to 24 hours. This is approved by the WHO and is a safe method.
Ewan, don't bother inventing sleep crutches unless you need them. You might be lucky and have a baby who will sleep. If not, then experiment with Ewan or whatever.
next to me, don't bother if you already have a basket.
Video monitor - virtually useless for a small baby. Initially they should always be in the room with you when sleeping. When slightly older, a sound monitor is probably enough as a baby laying on its back doesn't do much to see. A video might come in handy with a much older baby/toddler if you want to check what mischief they are getting up to I guess, if you leave them to self-settle or whatever. But I've never used a video as I find it would be very invasive to think of someone videoing me while I slept, so I would not like to do it to my baby either without strong reason. I know that argument probably sounds crazy but for some reason, it matters to me. Also, if you check it and see a baby lying still, then you're likely to still want to go stand next to him to check he's still breathing before you go to sleep yourself so the monitor itself is a bit redundant.
Best wishes.
