Heres a though on Momo, his dad was a contempory of Gol D. Roger which would make him Garp and WB's age approximately who are more like grand parents. Also Momo gimmick is being all over the ladies and gets away with it since he is a kid. My theory is he is not a kid, that through some interaction with Jewelry Bonnie he was made younger for his protection, or some other plot reason. This would explain his attraction to the ladies and make for a hilarious moment when Nami and Robin discover and beat the heck out of him after he is turned back to adult! :)
