Your Baby's Hormones and their Sleep

Your Baby's Hormones and their Sleep

We’re continuing our dive into sleep for littles on the Mossy Log Blog.  Today’s guest post is brought to you by Kim of Limestone Coast Sleep School in Mount Gambier,  Australia.  More details down below about her and her excellent work.

From the 60th day of life, your baby’s pineal gland is developed enough to begin producing and releasing their own serotonin. This in turn means that they can produce their own melatonin. It is a time where we see their sleep cycles maturing, and their hormone and neurological development becomes more ‘adult like’ than newborn. 

So, how do these hormones impact on sleep? And how do we use them to our advantage, wherever possible? 

✖️The wake and stress hormone is known as cortisol. It works in conjunction with the sleep hormone melatonin - balanced throughout the day to keep us alert and awake, until we are ready for sleep.

✖️In terms of the stress hormone, it is released at a point when the body becomes so fatigued, in order to keep us alert and vigilant. This keeps us awake, alert and can create a second wind type feeling. For babies, it is a cause for fighting sleep, and is commonly seen where babies have bee awake for too long between naps, or haven’t slept and have therefore becomes overtired. 

✖️It can take 1-2 weeks to knock back this overtired feeling and hormone in babies, especially those who have never really slept well.

✖️The happy hormone I better known as serotonin, and this hormone is key to achieving sleep, as serotonin is converted into melatonin when the light is cut. This is where we use our holistic approach towards sleep, by incorporating nutritional components which can in fact support the sleep neurotransmitters, and that conversion forwards melatonin.

✖️When serotonin is converted into melatonin, our bodes begin to see a drop in temperature, moving towards sleep. 

✖️Our sleepy hormone is known as melatonin, and as previously discussed, it’s a huge contributing factor to sleep. It is a hormone that can be artificially enhanced through the darkness of a room and plays a big role in assisting with the development and foundations of establishing your baby’s biological clock. 

✖️If your baby is getting good amounts of daylight when they wake up first thing in the morning, this triggers a shut off of melatonin, and tells the body that sleep is over, and wake time is upon us. 

✖️So, sleep in the dark, play in the light! It is highest at round 6pm, where we are biologically programmed and wired to sleep, not being nocturnal!

✖️The melatonin hormone is a key hormone for our sleep/wake cycles.
