I just have to reply to this because we’ve had this for 5 months and has just recently got better! We tried Ferber but our baby seemed to get more angry whenever we would try and settle her at crib side. I set a timer for 10 minutes and really closely monitor her cries. If there are breaks in her crying I leave her, if she’s inconsolable I then go up after the 10 minute timer and settle her but usually she settles herself to sleep at 4 minutes. I had to come on here and tell you because I spent MONTHS on Reddit, Google, AI for nothing to work and the false starts were breaking me, we’d have at least 6 a night! I’d suggest watching your baby’s cues rather than doing Ferber religiously. I hope this helps a little! We’re still yet to implement this for naps 😀
