Uy, I'd suggest talking to your pediatrician about this one, lang, better to be sure, especially kung may any concerns ka about your back or your baby. Honestly, a few of us moms try to avoid heavy lifting after birth kasi ang dami pang healing, pero every mama and baby situation is different, so best talaga marinig from your doctor kung okay lang for you specifically. Sabi ng OB ko dati, it really depends on how you're recovering and how you lifted it. Wag mag-worry muna, madalas fine lang, pero peace of mind is worth the quick check-up, di ba?
