Ah, trying for baby #2 na! Honestly, ang pinaka-importante ay track your ovulation, if you're not doing that yet, start with an app like Flo or even just marking your cycle sa calendar, kasi mahirap magbaby if hindi pa kayo nag-time ng tama. A few of us mums tried din na mag-vitamin supplements like folic acid at prenatal vitamins even before getting pregnant, at nag-help talaga, plus it's good for your body anyway. Make sure din na relaxed kayo, stress talaga nakaka-affect, so kahit busy with an 18-month-old, try to enjoy the process with your partner, and of course regular check-ups with your OB para ma-rule out any concerns. Good luck sa second baby journey, mama!
