Finding green poo in your baby’s nappy is usually nothing to worry about. Lots of things can cause it, including some types of formula. In the first few days after birth your baby’s first poo, known as meconium, can also be a very dark green colour. Do see your doctor if you notice any other symptoms though.
Then, can overfeeding cause green poop?
Lactose overload can result in an unsettled baby with adequate to large weight gains. The baby usually passes urine more than 10 times a day and has many (often explosive) bowel motions in 24 hours. They may have green, frothy poos that resemble those of a baby with lactose intolerance.
Beside this, why is my 2 month olds poop green?
Excess bile can cause green poop. A breastfed baby’s poop, as it transitions from meconium to mature milk, may look greenish. Green poop may indicate a foremilk/hindmilk imbalance in breastfed babies, which results in your baby is getting a larger portion of foremilk (watery milk) than hindmilk (thicker, fattier milk).
