If your baby has swallowed pool water, it is important to monitor them for any symptoms of illness. Normally, swallowing a small amount of water is not harmful to most healthy babies.            However, pools can contain chemicals, chlorine, and other harmful chemicals that can accuse stomach upset, diarrhoea, and other digestive symptoms in some cases.           Pools can also contain harmful bacteria, microorganisms and viruses that can cause illness. If your child experiences any unnecessary symptoms after swallowing pool water, it is best to contact their doctor. In the meantime, make sure they drink plenty of fluids to stay hydrated.
