Pregnant and breastfeeding?

BB

Anyone else pregnant and breastfeeding? I’m worried about my supply. My baby is 9 months old and only eats solids twice a day. She alittle underweight so I hope to still breastfeed as long as I can. I read your supply will most likely decrease around 10-12 weeks. Drinking as much water as I can, eating healthy and I sleep over 9 hours a night. Would love to breastfeed all throughout my pregnancy and eventually tandem nurse.
