When the environment is too stimulating, your baby might have trouble calming down. This can make it hard for her to get to sleep when the time comes for bed. She might become hyper-alert, fidgety, or even anxious.
Their growing brain can start to be overwhelmed by all of the new signals it is getting. Each experience and new sensation is another neuron firing. All of these exciting her experience are building strong networks in her brain, which is essential for brain growth.
But babies need a break from all this stimulation in order to process everything. During sleep, the brain has the job of cleaning up all of the construction in the neurons. Memories are processed, experiences are filed away, and the brain cleans itself up from the waste by-products of the energy is used.
Reducing stimulation close to bedtime can help their brain enter a tranquil state. Stimulation comes in the form of sounds, talking, books, toys, turned on televisions or screens or talking faces looking at them.
