Aww congrats on your baby boy! For M, a few of us mums love Mateo, Miguel, or Marco, timeless and easy to spell, while for L there's Liam, Lucas, or Luis na very popular dito sa Pinas. The best tip I got from my mum friends is to say the name out loud with your last name kasi parang iba talaga ang dating pag naririnig mo na complete, and check kung okay ang initials din hehe!
