Is getting an ear piercing for a baby girl really that painful?

Here are two baby girls getting their ears pierced. Meanwhile one cries badly afterwards, another one is laughing for some reason. Assuming they numb the ears, is it really that painful? My older cousin is getting her 5 month-old daughter ear piercing. She wants to make her feel as comfortable as possible.

It would be great if she reacted like the 2nd baby, happy and laughing but depends on pain tolerance I guess.
