when is ok to get your baby's ears pierced?

I'd like to get my daughters ears pierced. She's 2 months old as of yesterday, she has a dr appointment Friday so I'll be asking her dr as well. She's getting her shots. I want to get them done in about 2-3 weeks, she'll be nearly 3 months old and her daddy wants to be home for it, before he goes on his year long deployment in 4 weeks.  
When did you get your babies ears pierced? 
When would you recommend?
How was the healing process? 
Any hate, don't comment. 
Thank you!
