First of all, I'd advise her NOT to take antibiotics during delivery unless it's a life or death situation... They're routinely prescribed for women who've been labouring for over 18 hours after their waters have broken in the UK!
Obviously, interventions sometimes are necessary during birth, but trying to birth naturally (in a squatting position) rather than on ones back on a bed etc. helps with the birth and the recovery after birth.
Good breastfeeding support is a MUST!!! I'm in the UK and we have breastfeeding support networks, but it's hard to find good support after birth on hospital wards when mother is feeling very vulnerable - especially if the birth wasn't great.
So, breastfeeding support - if a supplement needs to be given, then try not to give by mouth or certainly not by bottle - a supplementary feeding system or a cup will be better than a feeding teat.
Invest in a sling/baby carrier as baby benefits from skin to skin contact as well as being able to get stuff done while baby is attached (it's amazing what you can do with a baby on the front of you :-).
Rope in as much support as possible to get some food cooked and frozen ready to defrost and shove in the oven/reheat. This is major issue! It is so hard to get much done when there's a baby around. Are you able to help out by making any meals that she can store for reheating/cooking?
