In Bali baby girls ears are pierced almost immediately, it's like their custom where all babies have their heads shaved (except a 1-2cm fringe :shock: ) at their 6 month (7 months to us) Ceremony...
We did not do this, but Mum & Dad in bali did a ceremony & gave hair to the gods from themselves for Indah's 6 month Ceremony!

(not entirely about piercing, but just another thing we do differently)
