Ashton Kutcher and Mila Kunis Look Overjoyed Grabbing Breakfast With Newborn Baby

Ashton Kutcher and Mila Kunis now have 2 kiddos hanging off their arms ... and they couldn't look any happier for it.

Paps got the couple grabbing breakfast Sunday morning in L.A. with their kids in tow -- 2-year-old Wyatt held hands with mom ... and newborn Dimitri got cradled by his pops.

Kids ... what a joy.
