Wow, a lot of healthy debate as usual on Mumsnet gone on over night!
I'm very proud discussion about these things but I am definitely personally sticking to the method we used last night.
I know she is not hungry at night any more, which is why I thought teething possibly (arnt they always teething!). I know this because I know my own baby and was ready to try something else.
Any way, she woke at 4, my partner went in, timed 5 minutes (she grumbled but no actual crying) he went in, then set timer for 7 minutes and after 3 minutes of grumbling she was fast asleep. Just had to wake her up myself at 7 for a feed.
If she was hungry she would have let me know so I will continue this method. I will obviously feed her if she is distressed or hungry, but it's going really well.
I feel she is ready as I explained earlier that she doesn't actually wake up, she just fusses and squarks hourly after about 3am, and had started waking at 11pm aswell as not self settling when we put her down.
She is on the 98th centile so thriving
