Both my and DH's parents co-slept, EBF, and CD'd. My mom even homebirthed in a time when that was really, really unpopular. She offered to help pay for a homebirth with my first but I was a little freaked out so I didn't - I'll ask her if she'll help me out with the next one, since I'm not freaked out anymore. And my in-laws used EC (elimination communication) with their boys, using diapers until 9 months only because of extensive travelling, but going diaperless after that.
My and DH's parents are probably the only people in the world who would look at us like we were nuts if we bought a crib :-).
And they are all GD'ers, too :-). FIL in particular is known as a kind of master of redirection - he used to take his kids to concerts (he is a concert pianist), movies, fancy restaurants, etc, and the kids were known for behaving - but it was really FIL being able to move their attention from thing to thing all through the event and keep them occupied.
My daughter, 3.5 yo, stays with my dad or my MIL sometimes, and they always just have her sleep in their beds, even though both houses have plenty extra space.
Both families have a kind of they'll-leave-when-they're-ready philosophy, and that meant that kids were between 3-6 when they left family beds. They expect us to do the same. We'd never hear the end of how mean we were if we tried to get the kids out of the bed before they chose it on their own.
Mama, homeschooler, midwife. DD (13yo), DS (11yo), DD (8yo), DD (3yo), somebody new coming in November 2013.
