You don’t need to visit the hospital for simple cold, cough, gassiness or even fever. But, if your child has a high fever or a fever that lasts for more than 3 days, it’s a good idea to get your baby checked.Apart from this, if you observe any serious conditions like breathlessness, seizure, or in cases of accidents involving a deep wound, burns or a bad fall, you should take your child to the hospital.
