How do I start to wean?

[MrsAxilla]

Stella is a year and I'm ready to start weaning her a bit.  I've done some googling and I get that I'm supposed to drop a feeding, but I have no clue how.  Right now she nurses four times a day:

5:30-ish am (if I nurse her then, she'll sleep another two hours)
AM nap
PM nap
bedtime

occasionally she'll want nurse again randomly, but not often.  

I SAH, so the nap time nursing sessions seem the most challenging.  The early am feeding might be the easiest - I can send DH in to do our MOTN waking routine, but she might also decide that she's up for the day if she doesn't get to nurse.

Suggestions?  What did you do?

thanks!
