People are always giving new mums self-pampering kits and 'luxurious' bath stuff - but, at least IME, you never have the time or energy to use them, and you can't use the bath stuff in any case because you're too sore.
Delightful but vaguely practical stuff, especiallly of the sort you yourself would never buy is great - my sister bought my LOs clothes from Monsoon and White Co when they were new/still tiny.
One of the best 'gifts' we received was when friends cooked a slap-up meal, brought it over to us, served it, ate it with us, and did all the washibg-up afterwards. That was a real treat.
