Uy, Yul is such a strong first name! Honestly, a few of us mums have been going through the same thing, and it really depends kung ano ang vibe mo, if you want something classic Filipino na sumasabay well sa Yul, like Yul Marco or Yul Miguel, malakas ang dating; pero kung gusto mo modern pero still goes well, Yul Adrian or Yul Dominic ang isa naming friend ginamit at ang ganda talaga. What's your last name though? That'll help narrow it down kasi mas makikita mo kung smooth ang flow ng buong pangalan!
