By what age/month did your LO had their ear pierced?

My baby got her ears pierced when she was 3 months old. The same nurse who assisted me during delivery was the same one who did the piercing. I personally asked her if it's still good to have the baby's ears pierced that time as compared to right after delivery. She said actually the earlier, the better as 1) baby's earlobes are the softest when new born 2) when baby's older tendency is she will move and make fuss more that you might have difficulty to make her still. I was not allowed to enter the room where the procedure happened and I felt so guilty as when it's done, my baby was delivered to me with tears in her eyes. :'( It surely hurts the baby regardless of the age it is done to them so just do everything to comfort her after.
