My 3 and a half year old goes to bed at 7.30 and i had thought that by the time my DD was 6 months and sharing with DS (next month) she would have a proper bedtime. But while she often has a nap about 7, she is wide awake within half an hour. I try to put her down again at 9.15ish as this is the time most likely to work but it can still take ages so i sit upstairs all evening (she feeds to sleep - I honestly don't know how else to get her to sleep. I did this with my DS and he learnt to self settle eventually, but i don't remember him having late bedtimes at this age.) She then wakes three times which are quick but takes any peace and quiet all the way through till 11pm, MY bedtime! She has 3 daytime naps of 30 - 45 mins usually - i am trying to follow her pattern, except I now want that pattern to include an actual bedtime!
