I'm a bit half and half here - some things I do, some I don't (I have one son who is 10 mths old).
I did the following:
Sterilised bottles (but not spoons, bowls etc) until about seven months.
Baths every night.
Clean, ironed clothes every day (I even iron muslins and bibs).
Reading to him from the day we got him home from the hospital.
He was in a routine from the day we got him home and has slept from 7pm-7am since 11 weeks and he's still in a routine.
I say no to him, now that he's mobile.
Things I didn't/won't bother with:
Stair gates.
Baby Monitor.
'Approved' food - he eats (more or less) what my husband and I eat.
Mother and baby groups - I went once or twice and neither he nor I enjoyed them.
Things I did/didn't do that really annoyed my health visitor:
I weaned him at 13 weeks (he was and is a big boy and he was starting to grab food and put it in his mouth) on the advice of my GP.
I didn't breastfeed - he went straight on the bottle after my elective (for health reasons) c-section.
Left him with a babysitter (my mother) at 6 days old to go out to dinner with my husband who was flying back down to London for work the next day.
I haven't had him near a clinic since his last immunisation.
