Need help with how to round on unit as manager......

I'm a fairly new manager who came up through the ranks, I.e. was staff nurse, than clinical leader, now manager. So I know all of the staff well, some better than others. I'm finding that rounding on the unit, (asking how things are going, generally talking to people, letting them know I care about day to day things..) is very awkward, for me and them. I think they feel like I'm "checking up on them." What can I do, ( and what do you do?) to make this better? I've looked in numerous places for info on this subject, there isn't a whole lot out there. Thanks for your help!
