I've had a cot next to my bed with all 4 of mine, but never had a c/s.
You can have the base of the cot raised to bassinette height & I don't put the side up just yet. Its high enough that she won't roll out (she doesn't roll around yet anyway), but low enough for easy access.
I also have it close enough to my bed that I stand up, pick her up & lay back down again. I don't have to walk between my bed & the cot.

I never saw the point in having a bassinette that you can only use for a few months. But then, I never in my wildest dreams thought I would have 4 children!
