Baby reflux is when a baby brings milk back up during, or just after, a feed.
Reflux is very common and it effects around 4 out of 10 preschool nursery babies under a year old. It usually starts before the baby is 8 weeks old and usually no test or treatment is needed.
Reflux is caused when the ring of muscle between the oesophagus and stomach is not fully developed, resulting in food or milk traveling back up the food pipe.
Other potential causes for reflux can include an intolerance to milk protein or allergies.
Reflux usually gets better on its own and often by the time a pre-school nursery baby is one years old. That’s because over a baby’s first 12 months their digestive system naturally develops and they spend more time upright as they start to sit up.
While there are some recognisable signs of baby reflux, it isn’t always easy to decipher as many of the common signs tend to mimic those that show your child may be distressed for any number of other reasons; for example, they’re hungry, tired, need a cuddle or they’re cold.
Sometimes babies may have signs of reflux, but will not bring up milk or be sick. This is known as silent reflux.
You do not usually need to see a doctor if your child has reflux, as long as they’re happy healthy and gaining weight.
