DS4 very suddenly just got bedtime. At 14 months
. Halleluja!
This is after 3 older children who were variable sleepers but nowhere near as bad as he, rocking to sleep, singing to sleep, letting him sleep on me, BFing on demand, topping up with FF, not feeding on demand, trying him in a hammock rather than cot, co-cleeping, attended a sleep clinic, CC, and in desperation CIO (except he did not stop crying, so did not 'cry it out'). Nothing made any difference to him.
We have not changed a single thing of our bedtime routine, which has always been quite consistent: with having to get 4 boys to bed there has to be an Order to things in the evenings
. And quite suddenly something just seems to have clicked: He now clearly recognises it's bedtime, has his milk, a quick cuddle, when I stand up to put him into his cots he kind of leans into it, assumes his sleep position wide awake and Goes To Sleep!
Do not be ashamed or defensive about your parenting. Although there are certainly things that can make sleep harder or more difficult to achieve, you cannot make a LO sleep. She will find a way in her own time. It is hideaous while is lasts though, huge sympathies.
We have now at most had maybe 1 nighttime wakening (from 3-6 until 2 weeks ago) and I am only just beginning to feel human again.
