I got both of my daughters ears pierced (ages 5 and 7) 9 weeks ago. They wore the gold post earrings for 8 weeks and I cleaned them as instructed. Everything looked great until we tried to change earrings at 8 weeks. When I took the earrings out, it was really hard to put in the different pair on one of my daughters, like it wouldn't come out through the back. On the other daughter it was easy, she keeps switching earrings everyday but today it was really hard to get it in and it bled a little which got her a little traumatized and sad since she wants to change earrings everyday and were told that after 8 weeks it's ok. Can someone explain to me what is going on? When it doesn't come out the back, I start again trying to get the right angle, it's so hard though and she is super sensitive so it's really hard to keep doing it. Any tips, ideas on what to do? I keep cleaning them and make sure there is never a moment that the earrings are off so not to close up.
