Mamas that co-slept, how/when did you decide to transition baby to the crib?

We've been co-sleeping since about December because that was the only way we would get any sleep. LO has been waking frequently, but he is also teething more, crawling, and attempting to cruise. Currently he has a cold as well.

I'm just wondering if there are signs they are ready to transition to sleeping alone.

TIA!
