Hi mama! Para sa 32 weeks, ang 1.8 kilo ay slightly on the smaller side pero hindi pa alarming, yung baby pa lang talagang gumagrow ng parang bili bili hehe, especially in the last weeks of pregnancy. I'd really suggest checking with your OB about this talaga, kasi sila lang makakaprecise based sa ultrasound and your baby's growth pattern, para sure lang na lahat okay!
