Sleep training can be a false dawn, because you habituated the child to a behaviour pattern, rather than them actually learning to sleep. When something changes (holidays, growing, etc) they still don't have the actual ability to sleep (because they never had it, only a behavioural adaption to circumstances as they were.)
Very insightful. I've not really put it into words like that before, but this perfectly describes my philosophy with teaching a baby/child to sleep.
Thank you FATE for all your fab advice - I've been on this board under many names. Ds is now 20m and actually likes sleeping. In his own bed. Amazing...
Thank you for your kind words Anatidae and great news about your son.
Loads of folks use several IDs on the sleep board and think I don't notice. (OP has also used several IDs). I don't know why. I assume to do with the wider use of mumsnet? Or maybe it's to do with how previous threads develop here. The benefit of hindsight might change people's perspective of my advice. Who knows? I rarely pay attention to username anyway, but usually recognise the habits of a child I've advised about before.
cantlivewithoutcoffee - you're sleep consultant is wrong on the wake-up time issue. (And whilst it got you out of rock bottom, is also not helping you enough to develop long term healthy sleep habits)
But my advice is free so maybe it's worth less than someone you pay? I don't know how much you are paying the sleep consultant - but he/she should be helping you develop some flexibility with baby, whilst still maintaining routine, structure and sleep associations.
Children cannot tell the time. So a child with healthy sleep habits (rather than forced behaviour associations) wouldn't realise that nap time is happening an hour earlier/later. As long as sleep associations are applied (cot, curtiains closed, sleeping bag, comforter etc) - there is a good two hour window between "just got tired" until reaching "over tired".
While this doesn't solve the sleeping on the move issue, it allows for some flexibility for things like holidays and special occassions. It also means that baby can do things like catch up on lost sleep.
The wedding for example. I would shift all baby's naps an hour (or more, if I think child can do it) later for the day. This might give me 2 or 3 hours for bedtime to be later. Then the following day, move naps earlier, say half an hour less awake time. This allows for baby to catch up from the out-of-routine day previously.
What you sleep trainer is doing is exactly what you paid him/her for. She got your baby sleeping at the time you paid her. That's actually quite easy - know the timings that allows for as little sleep as possible but avoiding over tired, so getting to sleep is easier because child is very, very tired. Gina Ford's book is based on this principle and it is usually the reason behind controlled crying (or call it "delayed soothing") working too.
These are very different to encouraging plentiful sleep by teaching healthy sleep habits though. But the long term view tends to not show the quick fix results sleep consultants are required to provide.
