Newborn Sleep Patterns

This post may contain affiliate links.
Despite the fact that we all sleep daily, sleep is not necessarily "intuitive" for us. There are many facets about sleep we don't understand in ourselves (What time is best for you to go to bed? What time to wake up? How many hours are best for you? Do you sleep better with or without socks? etc.). Figuring out the sleep of your new baby can be quite the project.

Newborns usually have a regular pattern to their sleep, and understanding that can help you in understanding what is going on and what you can do to help facilitate great sleep.

1-Newborns Make Noise Often, But That Doesn't Mean They Are Awake
A brand newborn is usually super noisy when first born. They make all kinds of grunts, sighs, "huh's"... They couple these noises with eyes fluttering open and often smiles. It is adorable! It is fun to watch, but do not get baby up every time you hear these sounds. This is just a noisy part of the sleep cycle. Let baby continue to sleep unless it is time for baby to be eating anyway. 

2-Sleep Cycles Change Every 45 Minutes
A newborn goes into sleep in REM sleep (See Healthy Sleep Habits, Happy Child page 59). About 45 minutes into a nap, the baby will transition into non-REM sleep. These transitions happen about every 45 minutes. At the 45 minute mark, your baby will stir. Your baby might make noise and might even open her eyes. Your baby might just shift slightly. Do not mistaken transitioning for waking up. Let your baby move into the next sleep state. 

3-Body Temperature Influences Sleep
Healthy Sleep Habits, Happy Child talks about biological rhythms starting on page 50. One influence on sleep is body temperature, and this remains true even up to adults. There isn't a way for you to really measure or respond to this, but know that as a baby gets to about 6 weeks, baby's temperatures start to get closer to what is best for longer night time sleep. There are biological factors out of your control that will impact how well baby sleeps at night. 

4-Melatonin Impacts Sleep
Melatonin is a hormone that comes from your pineal glad. Melatonin helps control your sleep and wake cycles. A newborn is born with "high levels of circulating melatonin" that came from the mother while in the womb. That is present for the first week. This is when you should sleep ;). 

After a week, all of that melatonin wears off and the baby is left with...not much. Around 6 weeks old, "melatonin begins to reappear as the baby's pineal gland matures" (page 51). The levels are "extremely low" until 12-16 weeks old. 

You can see from those numbers that they coincide with ages that babies start to sleep better. 6 weeks, followed by about 12...sound familiar? 

And do not decide to give your baby melatonin to induce more sleep. It has not been tested on babies. Also, I have to think there is a reason babies were designed the way they were designed by someone smarter than we are, so don't medicate or supplement your baby against what every healthy newborn baby naturally does--decrease melatonin levels. 

5-Newborns Do Not Stay Awake Long
Your newborn will be up for a very short time before needing to nap again. Your newborn will be awake anywhere from 30-60 minutes, including feeding time, before it is time to sleep once again (see my post Optimal Waketime Lengths to figure out how long your baby should be awake). Do not fight your baby on this. Let your baby sleep and your baby will sleep better overall. Overly tired babies start to sleep very poorly. 

If you want more time with your baby, you can absolutely hold your baby sometimes. It is wise to be aware of the amount of time since baby fell asleep. Do not try to put baby down in her own bed right around the 45 minute mark. This will likely wake her up since she is transitioning. Put her down before or after the transition if you are going to. If you hold your baby through the transition, do not try to wake the baby up during the transition. Let baby get into the next sleep cycle. 

I hope this information helps you understand the sleep of newborns a bit better.

Hi Val,

I'm so glad I found your blog again. I referred to it all the time with my now 6 and 4 yr old boys. We just recently had our 3rd, a girl, and I've been coming back to it again.

As soon as we got back from the hospital, I've been doing a 3 hr pattern with her. It was a little rough the first few days with naps and night time, but she's in her 2nd week now and I already see that she eats full feedings every 3 hrs and we've been really trying to encourage full feedings during the day.

Last night, her last feeding was around 7:30 and she has a really hard time going to sleep after that. We aim for 8:15-8:30 but she'll only sleep if she's held that time until the dream feed. Then after the dream feed, it takes another hr or so to sleep. Once she was asleep, she went until 3:30am, we fed her, and she woke up at 7:30am. She skipped a feeding on her own and we started her day like this, this morning. I was waking her at 8:15-8:45 since we've been home from the hospital.

So my dilemma is, do I just adjust her day from 7:30 from now on and try to squeeze in an extra feeding? Because she skipped a feeding at night, she only got 7 feedings. I really wanted to make sure that she got at least 8. I'm not sure where I could squeeze an extra feeding in. We did 7:30, so I'm assuming, I'll do every 3 hrs until the dream feed. Or should I wake her at 2.5 hrs to get another feeding in somehow? OR do I offer more at the feedings? She is formula fed. It's been a while since I've done this, so I've searched high and low for answers, but not sure what to do. My boys were up at 3 hrs like clockwork and our little girl seems pretty easy so far. I have to wake her for every nap.

Thanks in advance for your help!
Geny

Geny,
My husband and I have a 6 week old and I wanted to share with you that we've never done more than 7 feeding with him. I tried at week 4 to add a feeding thinking he wasn't eating enough like the baby wise schedule says but it made baby out of sync and slightly crazy. It was a mistake on my part. So I guess not every baby needs all 8 feelings

GKim said...

Thanks for your response, Erica. Are you breastfeeding or formula feeding? These next couple of weeks I'll just continue to follow her cues. Wasn't sure if I should just offer more food instead or do the extra feeding. She went back to 8 feedings on her own. I guess that 7 feeding night was a lucky night for me since I got a little extra sleep. :)

GKim said...

Sorry- another question. Do you have any resources or know of anyone who did formula feeding and Babywise. I found a blog called "My Devising" but was just curious if you knew of anyone else. Thanks!

Geny, if she does the 7 fine, I wouldn't stress about it. It sounds like she is back to 8 though.

It also sounds like she has witching hour at night. Be sure to read up on that if you haven't has that before.

Valerie Plowman said...

Geny, I don't know anyone off the top of my head who is a blogger. My Devising is written by Claire--she is great. You are safe with her.

GKim said...

Thanks for your response, Val! Yes, she is back to 8 feedings. I think the 7 was just luck and I got hopeful. It's hard being so sleep deprived and wanting just an extra hour or 2.

I will keep reading that site. I got a lot of good info from that too.

THANKS AGAIN!
