Ctelly, so glad you managed to get earlier scan! Must say I was surprised at hose formed my baba was at last scan...it never gets old

You're going to love it!!
I have a nanny and my mom lives with us...she works, but will help out evenings. I'm hoping she will stop working by the time baby is here though.
Each one of us will have different ideas and opinions, so use what you want, ignore the rest.
1. I only washed my newborns clothes with green sunlight bar, hand wash only as they can pick up all sorts of crap from residue in washing machine from adult clothes. When they hit about 3 or 4 months old, I swopped to Sunlight baby washing powder (blue box) and I think then I start using the washing machine.
2. When will baby start daycare? I'd say breastfeed as long as you can exclusively...it's easier. Less hassle than sterilising bottles (I breast fed one and bottle fed another, so done both).
Breastmilk stays fresh I think upto 6hrs (if not hot outside), but best to keep in fridge and then warm when needed. If in fridge, 24hrs if memory serves me correctly.
3. That is completely up to your baby. With Addison I used to write down times she fed, how long, when she slept, so I could work out her routine. As crazy as those first 6 weeks feel...they actually do have their own little routine already. So I don't think there is an answer here as your baby will be way different to the next person's baby
Hope that helps! And please ask away, we are here to help each other!
