We did a very gentle version of the Ferber method with DS when he was 7 months old, in addition to establishing a regular bedtime routine (bath, feed, story, bed). It took a couple of nights but he learnt to self-settle with surprisingly little fuss, to say we were previously co-sleeping and he was waking up every hour! Bedtime is now a lovely experience for all concerned :)
However, I haven't been able to do the same for daytime naps. He either has to be in the pram (with a blanket blocking out the light) or fed to sleep. Consequently his naps have always been fitful and easily disturbed, usually with two or three interruptions. He often wakes up before he is ready and he'll then be very tearful and clingy until he's fed back to sleep or taken for another walk.
I thought if I could teach him to self settle at the beginning of his nap - i.e. in his cot - then he might stay asleep longer and be properly refreshed, but the gentle approach isn't working, and I don't have the heart to let him cry it out.
Any ideas?
