Alhamdulillah syukur! At 4+ months, you're doing great lah dengan Obimin tu, yang penting consistency kan. Honestly for the second pregnancy, a lot of us mums just stick with our prenatal vitamin (Obimin tu dah cover the basics) plus make sure you're eating enough iron-rich foods, ayam, daging, leafy greens, sebab second baby pregnancy boleh jadi more tiring. Some of my mum friends swear by adding calcium supplement kalau takut kekurangan, esp since you're breastfeeding the first one probably, tapi that's something worth checking with your gynae first since every pregnancy lain-lain. Main thing is rest enough and hydrate, easier said than done dengan toddler at home I know!
