Ferber

Please rethink this method. It is absolutely cruel to let your infant cry when theyre basically begging for you love and closeness.
Your baby won't learn to self soothe, your baby is too young. It will just learn that asking for comfort is useless as you're not coming.

Im not making judgements, I'm just stating scientific research, bar the clueless but that's a conclusion drawn from the research.
Anyways, is your little one maybe teething?
Also crying while being held and comforted is very different for a baby than crying and being left alone. Everyone is different, I have been where you are and even now my little one will fall asleep in the carrier and stays on us for a while.
At the end of the day, it is your baby and if you're happy with your little girl shutting down because she knows no one is coming for comfort than that's fine but that is the reality of this sleep training method.

Have you looked at the course from “just chill baby sleep” it’s a sleep training course for babies 6m+ which teaches you how to teach your child to independently sleep and it’s a lot more gentler than Ferber, your child won’t be left to cry and it gives you two methods to decide which suits you best 🙂 it is tough when they are crying and not being able to soothe them but if other things are at play e.g too much day sleep, not enough day sleep, teething, learning new skills etc all the sleep training in the world won’t get her to settle easy so best ruling those out too 🙂

Yes I have to be careful because of IPR but it walks you through what you need to do to help your baby sleep independently there is two methods you can go through I chose the settling in cot one and it basically tells you what to do and how to respond, honestly it’s worth the money and my daughter responded really well to it as there was no crying and I always went into her
