What baby sleep courses actually worked for you?

Hey parents, I’m exhausted and desperate for help! My newborn just won’t sleep, and I feel like I’ve tried everything—white noise, swaddling, a bedtime routine, you name it. I keep seeing all these baby sleep courses online, but I don’t want to waste money on something that won’t work.

So, if you’ve actually taken a sleep training course that worked for your baby, which one was it? What made it different? And if a course didn’t work for you, I’d love to hear that too so I know what to avoid.

Bonus points if your baby was a particularly bad sleeper!

Thanks in advance—I just want a few hours of uninterrupted sleep.
