Ay mama, hourly pooping is definitely not normal, kahit low lactose ang formula, dapat hindi ganyan kalayo! One of my mum friends switched to a different brand kasi similar situation, and it turned out her baby had a sensitivity issue na kailangan i-address ng pedia. Since your baby's also acting fussy and different from before, I'd really suggest checking with your doctor muna para ma-rule out kung may intolerance or infection, dahil ang pooping pattern na yan plus the restlessness ay worth investigating talaga.
