Ay mama, I totally get the worry, 3.5kg is already malaki talaga at may almost a week pa! Honestly, ask your OB muna about your baby's position and if baby is indeed low na, kasi yan talaga ang game-changer for natural labor, hindi lang the size. A few of us tried walking a lot (like, mall rounds kina-three times a day haha), squatting, and staying active, pero truthfully every baby and every body is different, some just need their own timeline. The good news is na malalaman agad ng doc during check-up if baby is engaged na at ready; if baby is still high, that's actually common even with bigger babies. Try not to stress too much about the size kasi stress can delay labor, and honestly CS isn't scary as it feels right now, pero first, let's see what your OB says about baby's position at readiness. You're almost there, mama!
