I'v just gone through this with my daughter, she's 2 and was starting to wake numerous times a night and call out for me every time. I was getting no sleep and it was making everyone grumpy.
I tried a few things and a mixture of them seems to be working now. The main thing i did is the cry it out method, i felt really bad at 1st however, it was more protest crying and challenging the new process rather than actually being upset. 1st night lasted 40mins with several times getting out of her bed. 2nd night was 30mins, and we're now 5 nights in and she goes to bed quite happily without any tears.
I also got a Gro Clock, turned it to the lowest bright setting so it's just a dull night light really. I also give my child a coin, if she doesn't call me in through the night she can swap it for a sticker or treat in the morning.
1 of the biggest tips i found which has worked for us is that at a certain point in their sleep cycle they wake up and call out for some comfort / attention. If you stir them slightly (not wake them up) an hour after they've fallen asleep, this breaks that sleep cycle and they sleep through.
I also think it helps if you can nail them going to bed by themselves, then if they wake in the night they are better equipped to go straight back to sleep.
our routine is dinner, an hour later it's bath, PJs, 2 quick stories in bed, sleep. an hour later i stir her and go to bed myself. I hope you find something that works for you, it has changed our lives getting her to sleep properly
