Good morning doc.
Q: I’ve got a newborn turning 2weeks today. He’s been having running tummy yellow with somethings like white cheese. Is it normal. I am starting to get worried now. Another thing is that my stomach is been a little bit sore and its making noise(gas),n this is happening to the baby. Must I stop breastfeeding or what. Confused mum. Thanks
A: Dear mum. Congratulations on your newborn, and thank you for writing in. I understand why you’re worried, but let me reassure you 
First, let’s talk about your baby’s stool.
In newborns, especially those who are breastfed, it is completely normal to have frequent, runny yellow stools. The stool may also contain small whitish or seed-like particles, which many mums describe as looking like “white cheese.” This is normal and is simply undigested milk fat. It is not diarrhea and is not harmful.
Now about the tummy noises.
Babies’ tummies naturally make grumbling, gurgling sounds throughout the day. These sounds are caused by the intestines working, moving milk, air, and digestive contents along. You may notice the sounds more before feeding or shortly after feeding, and that is perfectly normal.
It’s also common for babies to swallow some air while feeding, which can lead to gas and more tummy sounds. Some foods can also increase gas, but this does not mean you should stop breastfeeding.
You mentioned that your own stomach is sore and gassy. Please know that a baby’s tummy noises are not caused by your stomach making noise, and this is not a reason to stop breastfeeding. Breast milk is still the best food for your baby.
As long as your baby:
Is feeding well
Is active and alert
Is not vomiting persistently
Does not seem to be in severe pain
then there is usually no cause for concern.
However, if you notice:
Blood or mucus in the stool
Persistent vomiting
Fever
Severe abdominal distension
Poor feeding or lethargy
please take your baby to see a doctor promptly.
And even in the absence of these external signs, whenever in doubt, it is always okay to ask and to seek medical advice. You’re doing well, mum. 
Have a lovely week ahead.
