IME the Wonder Weeks is spot on - DS's sleep / behaviour was messed up exactly when they predicted it would be.
At 10 months I probably wouldn't bother buying the book as it only goes up to 16 or 17 months, but even if you don't have iphone, you can sign up to a 'leap alarm' on the website where they e-mail you to warn you a fussy stage is coming up. I persuaded my local library to get the book too.
You can read more about sleep & developmental leaps here, here and here.
How they affect your child can vary too. The 12/13 month one was actually not too bad here, despite the 8-11 month ones being pretty horrific.
I've always taken a 'just feed and let DS get on with it' approach, although he's been a frequent waker rather than wanting to stay latched on. I did use NCSS ideas at 7 months which helped - but only till the next developmental leap when it all went pear-shaped again (and stayed that way).
After a developmental leap is the best time to try working on improving things. They can improve on their own though - at 13 months DS suddenly went from waking 3-5 times a night to waking just once (at my bedtime) with no intervention from me.
Now at 18 months he still sleeps much better even though I still offer a feed every time he wakes. The more recent developmental spurts have been much less painful than previous ones. And he now sleeps in the car which he never used to do, so it's all good. :)
