Well when I got them pierced (I was 11 years old) I had to change the earrings 2 weeks in because they were gooey and the hole almost closed up in the first 3 minutes! After the 6 weeks were up I could take them out for about 15 minutes at the most. I would wait for about 3 months (or something like that) because the holes close up VERY quickly. I am now 12 years old and I can take them out for at least 4-5 days but any longer and it is really hard to get them back in! You can take them out before 3 months obviously, but I would keep an eye on the holes though, as they could close up without you noticing!
