Are there any Evidence based infant sleep solutions?

Question

My 3 month old is starting a sleep regression so I started researching what to do. I noticed tons of products and programs and videos and systems. Everyone seems to have an opinion.
My husband and I both have data or research backgrounds and we couldn’t help but notice friends seem to recommend what “finally worked” for them but from a skeptical research perspective it’s just as likely that their baby just outgrew the problem. Classic correlation without causation! 
Does anyone know of a sleep method that’s backed by research (controlled studies). I don’t want to just start trying every for months until something seems to change.

Answer

Your babe is 3m old, still a newborn. Sleep patterns are going to be all over the place for the entire first year. Absolutely no sleep training until 6m at minimum. With regressions your just have to tough it out.

You might find this interesting "Development of infant and toddler sleep patterns: real-world data from a mobile application" https://doi.org/10.1111/jsr.12414
From the data depicted, a number of specific observations can be made. First, sleep patterns start to more clearly develop at 5–6 months. It is not until 5 months old that longer night-time sleep duration begins to emerge, with more distinct consolidation at 6 months old. Prolonged sleep durations also do not begin to occur for the majority of children, based on caregiver report, until 7 months old or later. These results are somewhat consistent with previous studies. For example, in a longitudinal diary study of 75 infants, consolidation of night-time sleep began between 3 and 4 months, with the majority of infants having prolonged night-time sleep periods by 3–4 months old (Henderson et al., 2010). Furthermore, night-time sleep duration in this study does not resemble a normal curve until 10 months or older, indicating the wide variability of sleep and skew toward shorter sleep periods prior to that age.

Answer

Highly, highly recommend Cribsheet by Emily Oster. My husband and I both come from similar backgrounds as it sounds like you guys do and we really enjoyed it

Answer

The “No Cry Sleep Solution” by Elizabeth Pantley is wonderful. She explains the study that they did in her book and the results of her method. We love it!

Answer

Sleep associations are still good to start (it's not sleep training). My now 6 month old has always had the same sleep practices and it has worked out nicely to let him know when sleep is coming. 
At nighttime, we put on his sleep sack and sit in his room with the lights off. We cuddle until he falls asleep or close to. We don't do cry it out or any sleep training yet but sleep associations. Hes been doing this since 2 months so he knows what going to his room (or whatever room you use) means. We also don't leave the room until morning as another association with sleep time. Naps are the time things. He typically falls asleep in 5-20 mins and can be transitioned to his bed from there.

Suck it up, that is the only method that worked for me😂😂😂

We used Little Z’s. You can check out the program online

Answer

Following this thread because I am curious about evidence based sleep methods too. Thanks for posting!

Answer

The thing with babies are, they’re all different. One thing might work for one baby, but not the next. What works for 100 other babies might not work for yours. It’s not as simple as finding something with proven results and it’ll work for your family. 
My biggest tip would be to pick something that fits within what you want to do, and what works for your family, and stick to it. Consistency is key with babies. And sleep regressions aren’t the best time to try something new. Usually they’re a fine where you just do whatever you can to get through it
