  1. I’d love to sleep although there’s those days when it’s hard to go to sleep either the mattress or the blankets or the pillows just trying to find that right position thank you for this great information….

  2. Cool way of explaining. We have a 7 month old who is up every 2 hours. I desperately need one good night of sleep. 😩

  3. Interesting. I think I am skipping a couple of these stages! I wake up so tired.

  4. Now I understand why I’m so tired every day. I toss and turn all night trying to find a cooler spot on my mattress.

  5. This is so me where did the hours go??? Sleeping is definitely a process. While many people experience different sleep patterns the process of sleeping is the same. Great information nice video 💤

  6. Excellent. Good information, enjoyably presented by the likeable young lady and the fun ” camera work”.
