Most days consist of three naps. These naps used to go, long, short, short. But over the past week or so we've moved up to two longish crib naps, 1.5-2.5 hours [often with a break in-between but only self-soothing], and one short nap that we share, her in the sling, me in the rocking chair, each evening just before Helena returns from work. This last nap allows Ivy to stay up until nine or 9:15 and get some quality time with Mitchell after he returns from work.
So far it's working well for everyone though I'd love to see Ivy get to bed a tad earlier and move toward giving up that sling nap, despite how much I enjoy it, I'd love for her to have a longer, deeper night sleep.
