the best time depends on the person, i change at random times after eating, after not eating, whenever i get a chance.
If you havent had the ostomy for very long it is going to be much more active at first. And it will get easier to change after a while, i promise, lol.
As for it touching the stoma, my wafer does and i havent seen a problem so far, noone told me it wasnt supposed to.
a good thing to do is have all your stuff out and completly ready before you start a change, have your wafer cut, your paste or seal or whatever on, everything ready!
I change mine in the bathroom and i stand on a waterproof pad, and i pull the bag off partway, clean around the top, then press on my stomach while the bag is still partway on and the stoma is hanging into the bag and any poop that is fixing to come out gets squeezed out that way.
Then as soon as i remove the bag a towel square goes over the stoma, my stoma is only uncovered or not in that bag for about 5 seconds. I lay down, stoma still covered, get my wafer and a clean towel square, pull the dirty square up, slap on the wafer then put the clean square on top. that way there is always somethign there to catch any poop!
