Tbh, I hadn't tried anything before. I walked/rocked/bounced her to sleep from an early age, for a few months between 4-7 months she needed hours of rocking a day

Between 8 and 10 months, she went to bed at 6pm and would wake every 30-90 minutes until 10 or 11pm (Noelle reckoned this was cause she was going to bed too early so we switched to 7pm bedtime which definitely helped some) and she'd wake up between 11 and 2 am and stay awake for 1-3 hours - she did that for about 2 months lol!!!! When she woke hourly or less one night, I decided enough was enough.
I bathed her, let her do her usual crawl around and play for an hour, gave her a bottle and put her in her cot. I just put one hand on her tummy, one on her head and stroked her hair and shhhed loudly when she cried and quietly when she was quiet. She was asleep in 15 minutes and cried a not too upset cry, on and off for 10 ish mins. The second night she cried for 3 minutes and no crying the third night. I've just been doing the same thing since, it doesn't always work straight away (if she's squealing and chatting it won't work) so I just walk away for a bit and on occasion she will self settle and if not, I go back in when she cries and shh and stroke her head and she nods off. She no longer wakes in the early night time and it's been 1-2 wakings since then and only a few, short motn parties
