I personally don't like the idea of sleep training so I didn't bother with mine. I know it worked for many people but it didn't suit us. If your baby doesn't respond, OP, don't worry, it doesn't mean anything except your baby is atypical in her sleep requirements. I took much comfort from the urban legend that the more intelligent the baby the less sleep it needed. It may or may not be true but what is really useful is to note that not all babies need the same amount of sleep.
My view was that I needed to learn what suited them rather than trying to teach them to do what I expected. I read a lot of reassuring material about this but the thing that really made the difference for my quality of life was that I stopped seeing sleeping as a 'problem' that I had to 'solve'. If the baby woke and didn't resettle with a boob, I got them up and soothed them. If they didn't want to be left alone I thought fine, they can come and be with us, they can nap in my sling or on my lap or on daddy's chest or whatever.
To me, the problem wasn't sleeping or not sleeping, it was crying or not crying. When in the early days with DS I was 'trying' to 'put him to sleep' and he was crying and I was wound up, in the end I just couldn't figure out why I thought was worth me lying around in an (artificially) darkened room thinking about what I was missing out on in the living room or letting my dinner go cold or missing reading a novel or talking to DP, just to make my baby cry in frustration as it wasn't what he wanted either. Specially as basically as soon as you think you've got it cracked they have a growth spurt or sprout a tooth or get a temperature and you are back to disturbed sleep and no routine. And it's so short, they're like this for the blink of an eye but then they grow up like the rest of us who just need and like to sleep at night and if something is going wrong in that can take responsibility for working through that themselves. E.g. my four year old can understand why good sleep 'hygiene' is good for him and asks to go to bed if he is tired; people like to have an early night if they didn't sleep well the night before or have to get up early. Let that natural wisdom develop, I say.
Why spend the teeny times trying to 'do' something to your baby that your baby can't or won't fit in with? If the child is crying then clearly you need to help remedy that but if 'putting the child to sleep' isn't working, just stop that and let them be with you, enjoy the cuddly time, know that they'll grow out of it. Mine are still slightly atypical in that they don't sleep as much as what people claim their kids are sleeping but so what? They are champion sleepers in that they'll stay asleep through the other one kicking off or a thunder storm or our neighbours' parties. And they'll ask to go to bed if they are tired and they sleep to a sociable time or will be happy to lie quietly with the rest of us if they have an unexplained wakeful period.
They'll learn about sleeping and night and day, and independence in their own good time, you only have to be there for them, soothing, reassuring, loving, comforting. The time when they are tiny is unpredictable in the short term but over pretty quick. Honestly don't try to fight them into something that doesn't suit them, you'll end up pissed off and they'll be distressed. I know that some babies respond to routines but mine didn't and if yours don't that is not because you have done something to them it's because they are who they are. If your baby doesn't respond to the routine or to bed time like mine didn't, the only thing that you need to do is figure out how to live your life with an unpredictably awake and unpredictably sleeping baby. Don't spend hours every night trying to cure them of who they are. She'll be toddling around this time next year - the year after you'll have to work to remember the baby that she was. You'll barely remember this conversation, or what you were thinking while we had it by then. Relax and roll with it, she may or may not get any more sleep but she'll have a happier mummy. Happy mummies inspire security, right?
