My mom was a single mom til I was 4 1/2 and I am pretty sure that we coslept occasionally, but also had a crib.( I have seen pics) when I got out of the crib, we shared a TWIN bed.
She got married when I was 4 1/2 and i got my own room. I dont even remember the transition.
We dont really cosleep unless coming in at 6 am and falling back to sleep counts.
Or if sleeping in the recliner or on the couch together counts.
My mom has never said either way, but i have a cousin who lost 2 babies when they were cosleeping, no other cause was ever determined. they ruled it as death by suffocation.
so it would be a slightly touchy subject I am sure if we brought it up or said we didnt get a crib or something like that.
I like your point though.
