i left mine in with dd, and to be honest, i forget that i still have it pierced!... lol

i have a very.. umm whats the word.. un-deep (LOL) piercing, its like 3mm worth of skin, so i just had a sleeper in it. i dont know how its managed to grow out so much, then stop where it is! i have a regular ear stud in it all the time, ill put a sleeper in once i start to expand

ETA: once my belly button has gone completely flat.. it looked like a surface piercing with a sleeper in it!
