My lo is now 19 months old. Was a nightmare sleeper - awake 1/2- hourly for about 4 months then waking up about 4-5 times a night from then on. I tried everything, everything and was absolutely exhausted. I'd try and put her to bed in her cot but she would invariably end up with dh and myself in our bed.
In the end I thought I would stop getting stressed about it and do what my instinct told me to do, not try and force any changes but leave them evolve on their own. I started to leave her in bed with us as she would sleep better. I learned to BF on my side (half asleep). I would often nap with her in the day - she would nap for 20 mins on her own - 2 hours if we both went to bed together. As I was so exhausted - I usually went to bed with her.
She started sleeping much better at about 11 months but would still wake once or twice a night and by 14 months was sleeping through completely. At 18 months I bought her a big double bed in her own bedroom. i thought I would have a bit of a nightmare getting her to sleep there (everyone told me I would never get her out of my bed as I had spoiled her!) However, she slept there all night on her own and woke at 8am.
Over the last month I have popped into bed with her twice as she had woken up crying (although 4 teeth have come out in this month!) but she has always settled back to sleep quickly.
As for the holy grail of getting your baby to fall asleep on her own - I have never been able to achieve it. I'm not concerned though as she only takes 5 mins to settle. I just give her a drink of milk and jump into bed with her. i then say 'shhh' a few times and she's asleep. I've previously always breastfed or rocked her to sleep.
She was also an early riser - 5.30 usually - has also on occassion been earlier - eeekkk. However, the last month on her own accord she's started to sleep until 8am - bliss!!
Before I had a baby - I was always of the mindset - babies should sleep in their own, cc was ok etc etc. Now I'm much more mellow and am a happier mum with a happier toddler because of it.
There is a fab book called - 'our babies, ourselves' which is written by an anthropologist/epidemiologist and despite being full of research - it's really easy to read. I't goes through what is normal behaviour for babies and why they behave in this way. It was very enlightening and really made me think about the fact that my baby was completely normal and I hadn't done anything wrong to her hence she wouldn't sleep. It's in amazon - I've lent it to a few friends who all think it's an amazing book and chucked their very well behaved baby manuals away!
Good luck with it - it will all sort itself out in the end. Try not to get stressed and just do whatever you feel will get you and your baby more sleep!
