PO*P REACTION TO FORMULA MILK

Good morning TAP Parents! I'm here to ask a question po regarding my 6 months old first formula milk. Nag switch po kasi kami since I'm currently pregnant and since may eczema si LO, nirecommend ng pedia niya to try NAN Infinipro HA (6-12M) However, this morning naging ganito consistency ng 💩 niya. While yesterday normal poop naman. 2nd day palang niya mag try ng milk. Possible poba na di niya hiyang?
