Thanks everyone...

I rang around few places... No age limits that i have found... 1 place said their gun was a bit big for little lobes but said they could use a special piercing needle... I'm not going for that option.

Another place said they prefer doing 1 side at a time as its more accurate... Cost about $30 bucks... Incl earings...

Cookiemonster... i could picture me looking at hossy tags also if i had identical twins...
