Your baby could be suffering from multiple reasons resulting in thrashing at night, and one of these is having night terrors. A night terror is a sleep disruption similar to having a nightmare but much more dramatic. They are noted in kids who are overtired, ill, stressed, taking a new medicine, sleeping in a new environment, not getting enough sleep, or having too much caffeine. Your baby will thrash around, but you have to wait patiently for them. It’s not right to wake up your baby too. A few things to help prevent night terrors is to reduce the causes in the first place. It might take some time, but it’s better to start taking action today.
