I second the recommendation for Precious Little Sleep. I bought and would recommend the book, but you can also get a lot of what you need from these blog post but the author. https://www.preciouslittlesleep.com/what-you-need-to-know-about-sleeping-through-the-night-part-i/ https://www.preciouslittlesleep.com/what-you-need-to-know-ab... That was enough for a while and I believe I didn't actually buy the book for at least several months. Then I bought it at 2am during a particularly rough sleep regression. ¯\_(ツ)_/¯ My main caveat for sleep advice is that you need to take it all with a grain of salt because whether any particular strategy will work depends on the parents and kids temperaments, along with a variety of other factors. YMMV and don't let anybody else's success story make you feel bad. They're probably leaving out the worst parts, possibly because their brains have literally blocked out the memories of them.
