Gina Ford does recommend controlled crying actually - she recommends a "20 minute crying down period" before intervening. As do other commercial sleep programmes ( Little Ones suggests 6 minutes I believe).
That's not what she says on her website:
My friend is following your book with her baby daughter who is now nearly five weeks old. She seems to cry for ages every time they put her in her cot. While I would like a routine, I do not want to leave my baby to cry for long spells. Yet several parents I have spoke to say that if you follow the CLB routines you have to be prepared to leave the baby to cry itself to sleep, no matter how long it takes.
This is simply not true. Nowhere in my book do I say that young babies should be left to cry for lengthy periods of time to get themselves to sleep. I do stress that some babies will fight sleep and they should be allowed 5-10 minutes crying down period. They should never be left for any longer than this before they are checked again. I also stress that a baby should never be left crying for even 2-3 minutes if there is any doubt that he could be hungry or need winding.
The ‘crying to sleep’ that some critics refer to is actually a method that I recommend to use with older babies who have reached six months or a year and are waking several times a night because they have learned the wrong sleep associations, brought on by demand feeding or being rocked or cuddled to sleep. In these instances I recommend a form of sleep training that has been used by childcare experts, paediatricians and Health Visitors for many years.
In my book, The Complete Sleep Guide for Contented Babies and Toddlers, I stress that sleep training and controlled crying is always a last resort to get an older baby to sleep during the night and should only ever be used once parents are absolutely sure that the baby is not waking up because he is hungry. I also advise that before commencing sleep training you should take your baby to see the GP to check there are no medical problems.
The reason that sleep training and controlled crying fails to work for many people is because parents read, or are told, that a baby over six months old does not need to be fed in the night and can sleep for a longer period. While babies over six months can, most certainly, sleep a long period every night, this will not happen if the baby is not eating enough during the day (and if the baby is waking up and feeding several times a night he most certainly will not be getting enough during the day to eat), so parents who use controlled crying can find that they will leave their babies to cry for many nights in a row but the problem will not be resolved because the baby is continually hungry. Resolving the hunger problem by ensuring the baby receives most of his milk between 7am and 7pm will eventually stop night waking.
In all of my books I include case studies where older babies are waking in the night and continually need to be fed. I explain how to gradually reduce the number of feeds in the night by increasing what the baby eats during the day. It is only once I see an improvement in the baby’s daily food intake (i.e. between 7am and 7pm) that I would then possibly recommend controlled crying and then only if I thought that the baby also had a sleep association problem.
The whole aim of the Contented Little Baby routines is to ensure from the very beginning that the baby's needs are being met so that he does not need to cry for any length of time. The guidelines I give are also to help mothers understand the different reasons why a baby may cry. If a baby is in a routine from a very early age the mother will quickly learn to understand and hence anticipate his needs. I have found that this results in the baby crying very seldom – around 5-10 minutes a day in my experience.
