Completely agree with Miss J. If you have certain antibodies or you have a RH negative blood group then your babies are more likely to have jaundice. Also like Miss J said if bubs come early then they are more likely to have jaundice then full term babies.
Every baby to a degree (even if you can't tell) has some degree of jaundice (according to the paeds where I work anyway) but obviously depends on the levels as to weather they will need phototherapy lights or bili beds. The more you can feed your baby in the first few days after birth (without making them spew of course) the more they poo and the more they poo the quicker the bilirubin is broken down. Also you can put them under the window in the hospital where they get some natural sunlight which will also help them break it down. Just a thought.
