Ohhh congrats sa baby boy! So cute na M and M pairing, parang candy theme haha, my mum friend did something similar with her twins kaya naka-relate ako. Some nice options: Mateo & Miguel, Marco & Manuel, Marcus & Martin, or puwede ring Mikhail & Maxwell if gusto mo mas unique. A few of us prefer names na hindi sobrang matching pero same starting letter lang, like Marcus & Maurice, mas distinct pero coordinated pa rin, you know? Depende talaga sa family preference mo and kung ano ang flows well sa surname niyo!
