I'm leery of co-sleeping mostly because it seems to be highly correlated with kids who have bad sleep habits and keep waking up their parents constantly (don't worry how you'll know, they'll tell you) well into their toddler years, and beyond. And I'm pretty sure the co-sleeping is a big part of the cause (can't get used to waking up mom & dad for entertainment every time your natural sleep cycle wakes you up a smidge if they're not there to wake up and start giving you attention instantly).

But like anything else, fuck, if it's working for you and the risk is very low, do what you need to do. I avoided it because I kept seeing hellish outcomes but if that's not what's happening for you, go for it.
