Newborn Poop

Hi mummies, my LO is 1 month++ old and he started to poop alot. Is this poop colour and texture normal? On the day, he is given breastmilk through bottles and at midnight he is given formular milk. Just a concern, as I am staying in malaysia for confinement. There is alot of flies and bugs in the house. If unknowingly, flies or bugs touches the baby feeding accesories or my pumping accessories. Will that be a concern?
