밤에 아기가 엄마 아빠 옆에서 자야 하는 이유 (뇌과학이 말하는 것)

What actually happens inside the bodies of babies sleeping alone versus those sleeping next to their parents? And what is the real science behind the saying, "Sleeping together at night is better for emotional development"? We break down all the rumors surrounding baby sleep using the latest insights from neuroscience. If you cannot sleep next to your baby due to circumstances, please make sure to watch until the very end. This video will truly lift a heavy weight off your shoulders. 📌 This video is especially helpful for: Parents raising babies aged 0 to 12 months (especially under 6 months) will find the core insights here. For parents with toddlers over a year old, this will also help you determine when and how to transition them into their own room. 💛 If you have been practicing separate sleeping until now: Please don't worry too much. Attachment isn't built on which room they sleep in at night, but rather through the countless responsive moments when you go to them whenever they call. A baby's brain is incredibly flexible, and your warm, loving responses starting from today are more than enough.
