do i need to worry if my baby swallows gum   

Generally, it is not harmful if the child swallows chewing gum once or twice. Children under 5 should not be given any chewing gums because they don’t understand the difference between swallowing and chewing. In case if they have already swallowed, there is not much to worry about. Chewing gum has a gum base that is indigestible. But it doesn’t stay in your child’s stomach. It moves relatively intact through the digestive system and is excreted via stool in a day or two. On very rare occasions, the large amount of swallowed gum can combine with constipation and block a child's intestine.
