BABIES ARE MESSY (AND THAT'S OK)
From a cute little spill to a tsunami overflow, most babies regularly bring up milk. This typically doesn't mean that baby has over-fed or there is a medical problem, and here is why...
The gastro-oesophageal sphincter, or 'valve' that stops the stomach contents from coming back up, is immature in young babies. Combine that with a maturing baby's increased activity and baby lying on their back, and you can see that it is easy for some milk to flow or "reflux" back up that short distance from a baby's stomach to their mouth (and nose sometimes!)
While a newborn sleeps a lot and doesn't spill much milk, in the following weeks and months spills and spews become increasingly common as baby is more mobile. If your baby is mostly settled and isn't bothered by the spill, overflow, or spew, and if their weight gains are tracking normally, you can consider this a laundry problem and not a medical problem.
