I got DD1's done when she was 12 months old, they told me then that the best time to get them done was around 3 months coz most bub's aren't rolling etc then. I got DD2 done at 3 months and DD3 done at 4 and a half months. I used the emla gel on all 3 girls and I have never had any dramas with them. The place I got my girls done had 2 piercing guns so both their ears were done at the same time. They all only cried for about 15 seconds and the staff (I got them done at a chemist) said that because they had the emla gel on they were most likely crying from the noise of the gun.
