First up, Simpson, 33, shared a scrumptious shot of son Ace, 9 months, curiously examining the ear of a beaming Rocco, the 8-month-old son of BFF CaCee Cobb and husband Donald Faison, during a joint bath.
"Bunny babies," Simpson captioned the aww-inducing photo of the next generation BFFs.
Two hours later, Simpson posted a sweet photo of daughter Maxwell, who turns 2 May 1, cozying up to cousin Bronx, the 5-year-old son of engaged sister Ashlee Simpson, during an egg hunt.
"BX and Maxi have the same shy face. Cousins!!" she captioned the shot.
Something else they have in common? Impressive egg-finding skills: both have baskets chock full of colorful eggs. Considering the two kids are holding hands, it looks like they found them in harmony.
