I thought the exact same thing as you 3mths ago. I did everything I could to get her to sleep on her own, tbh I can't remember what I did it seems so long ago .

I have tried wrapping we have a houdini who got out, not wrapping, crying it out, cuddling, rocking, walking, bouncing, ignoring, sleeping in our bed, on the couch, in her bed, on us, beside us, I can honestly say I think we tried everything. We tried her stomach her back and her side.

I asked on here and the advise I got from everyone was do what you need to do to get her to sleep. The more sleep she gets the better the sleep as sleep breeds sleep. It does get better and easier and tbh I find it hard remembering what those first few weeks were like. I have a nephew who is 6weeks younger then DD and see all the issues that my brothers gf is going through and remember my frustration. Advise for the night is when she wakes up feed her and if she is ready to go back to sleep then put her down, if not then do what you need to to put her to sleep. I stopped changing DD unless it was a dirty nappy and wouldn't interact with her and it got to the point where she would only be up for 20mins at most during the night.

If she wants to sleep on you then let her do it, but when you feel up to it try sleeping her in different places, I did this from the beginning and DD can sleep anywhere. Seriously for the first 2weeks I did nothing round the house but care for DD and then we slowly worked on doing other things its only been the last week that I have been able to do housework as up until then DD wouldn't sleep during the day and she is able to play by herself. I still struggle to have a shower most days as DD wants me with her all the time.

Try to let your partner care for her as much as possible and she will get used to being away from you. Little guy loves being held regardless of whos holding him and when he's with another female he gets booby cuddles lol its cute and he's comfortable although I don't get much of a chance to cuddle him as DD screams or cries whenever I take him even if she's asleep

So basically do what works for you until she becomes comfortable and secure then she will be able to go down on her own and if need be co-sleep with her, we do this everynow and again even last night as I was too tired to get up to her and settle her properly and keep up the good work

You're not likely to set any bad sleep habits at this young age.  Do what you have to do to get by for now with a view to encouraging your baby to sleep in their bassinette by 3mo.  You may find that she'll have some sleeps in her basinette and dead refuse other times, that's ok.  If you're comfortable letting her rest on you then do it, it's a great excuse to have a rest too or you can get a sling/wrap/frontpack so you can go about your day while she sleeps.

Google "the 4th trimester" and you'll get some great insight as to why many babies prefer to sleep on mum.  Basically the gist of it is that human babies are born too early.  Evolution has made our heads to big and pelvic bone too small so that if babies were born when they were ready they would most likely kill their mothers during childbirth   There's a lot of studies and opinions on the topic and it makes a lot of sense plus if you remember that Macy is for all intents and purposes still a helpless little foetus it will make you feel less like you're doing something wrong especially when confronted with unhelpful opinions (my MILs favourite was to say that I was ruining their bones by holding them while they slept it was very hard for her to back up that stupid comment when I pointed out there's nothing wrong with my 3yo who slept on me far more often, nor have I made a "rod for my own back" since she is a dream to put to bed and has been since I trained her at 10mo).

Emz I understand where you're coming from too and hopefully some of the things that worked for me will work for you.  Firstly I highly recommend you watch "the happiest baby on the block", when DS was younger we used his 5 s's (minus the dummy) to calm him down and send him off to sleep.  Once asleep it took 2 decades of the rosary (how ever long that is.... about 5-10 mins I guess) before he was so deep in sleep I could drop him from a great height onto his mattress and he'd remain asleep (not that I did).  His late afternoon nap he was impossible to get down and so I conceded that one and spent the time sitting in a comfy chair cuddling him while M watched tv. 

I started sleep training him when he stopped falling asleep easily using the happiest baby methods (I'd need to go back through my due thread to find out when that was but I think it was about 2 1/2 months old).  With sleep training it's completely up to you what method you choose (no-cry, cc, cio) you need to do what's comfortable for you but the most important things are consistency and confidence.  I'm not too keen on leaving babies to cry but have a cradle which meant I could rock him to calm him down without actually picking him up which I think helped hugely.   For us every bedtime has a set routine - read a story, swaddle, say prayers, sing a song as I put him to bed then turn on some background music (which is particularly useful to drown out household noises particularly the noise of an older sibling) that all takes about 5 mins so I'm not away from DD for long.  He now lies there quietly listening to music until he drifts off to sleep.  We sometimes still have issues with the last sleep of the day so I have a recording of me singing his bedtime song which gets put on repeat for him to listen to while he sleeps in his own cot.

I have heard one person use the trick of putting a watch in the cot/bassinet where baby was sleeping, one with a ticking sound so that baby had the feeling of having the tickinglike the beating of a hear. Maybe worth an idea

I forgot to add that I make Andrew's room dark for nap times (I use a blackout type curtain).  It's less stimulating and also a good sleep cue.

I second the miracle blanket, we swaddle with that and it's fantastic!
