I have 12 month old twins and hub and I have not had a full nights sleep since they arrived. Last night we did. A friend recommended a website www.babysleepanswers.co.uk. I have been using the system for a week (its really flexible because you can choose from a number of options e.g. controlled crying, no cry etc) and you get free online support from a sleep expert as long as you have bought the book - best 7.99 I've ever spent). Definitely worth a look folks.
Just got to get my 7 year old to stop wetting the bed now!
