Ay normal lang yan, mama! A few of us breastfeeding moms experience the same thing, parang may trigger kasi sa body natin during letdown, either nausea or intense thirst, it's all connected sa hormones at ang milk ejection reflex. Kaya mo yan, pero kung tumatagal or nakakaabala na talaga sa iyo, check mo lang with your OB kundi to rule out anything else, baka lactation consultant din pwede tumulong or meron syang idea kung paano manage yung ganitong feeling, pero sa karamihan ng cases it's just one of those weird breastfeeding things na nasasanay lang tayo hehe!
