Mama June's granddaughter, Kaitlyn Cardwell, is now bandage-free and showing off her solo thumb.
TMZ broke the story ... Kaitlyn's mom, Anna, made the decision last month to have an extra thumb surgically removed from the 4-year-old's right hand. The surgery went off without a hitch, and Kaitlyn's recovery went faster than expected ... so she got to ditch her cast early.
Kaitlyn's extra digit was a big talking point on the show, but we're told it won't be missed. Most importantly, she's feeling great after the surgery.
