Nevermind on the girl sucking her fingers. I see her thumb in the second link, that picture is of better quality. Still the hand is at an unusual angle.
Remember thouhg- kids can lift their legs over their heads without even usign hteir hands to help the leg- they are icnredibly flexible- UI just tried the backward hand and can do it, but it’s not comfortable, but I’m also way past beign flexible lol0-
Yeah, it does look strange, little kids are pretty flexible though.
As to dad's fingers being long, I've known guitar players that all have the longest, almost retarded finger lengths.
I say retarded because you have to be to make some of those cords, I've tried!!
LOL!
