Put them on their front to sleep so they didn't choke on vomit. The advice changed during the six days between being born, when she was carefully placed on her front by the midwives in the hospital to the first post natal midwife visit.
Put them in another room if possible at six weeks so they didn't get woken up by you. Put them to bed in the evening and then come back to have your evening meal/couple time in peace.
Don't ever have them in bed with you. Ever. Not because of squashing, not because of suffocation, but because they'd become 'a rod for your own back', especially if you made it worse by picking them up if they cried.
Give BF babies cooled boiled water at night from 6 weeks so they don't expect food and sleep through. If they wake up, you don't have good enough milk, so stop BF and switch to hungry baby milk at 8 weeks.
Don't ever, ever, ever, let the baby have a bottle from somebody else if you wanted to BF, as your supply would dry up and baby would prefer the teat because it was easier from just one bottle.
Thicken formula with rice if they still wake up. If they cry in less than four hours during the day, wait until they are crying properly before picking them up - or wait it out for the extra ten minutes until it's 4 hours.
Start giving them food by 16 weeks.
6 months BF was more than enough for any baby. In any case, you'll be back to work by 12 weeks, so there's no point in making it harder on yourself. If they bit you, it was proof that they were too old to BF anymore.
The weaning advice varied from 16 to 20 to 26, back to 16 and probably a few more besides in the five years between #1 and #2. And each time they would always deny that there had ever been any different advice, they didn't know what you were talking about and you must be mad. They also denied there had ever been any advice to lay them on their fronts.
The not picking up changed to never let the baby away from your body ever, take them into the toilet with you or they'll be distraught, don't let anybody hold them until they were old enough to cry at being away from you, etc. In the five years, this changed to 'they'll manage if you have a shower without them if they're safe in a cot or with somebody else'.
