DS, 15 co-slept till he was 5 and didn't sleep through until then now he is an awesome sleeper, DD 12 months will not sleep anywhere but her own cot, has never slept through she still wakes once every night. Im ok with this because for the first 10 months she was awake at least 5 times for reassurance or hunger. Some nights she will still have a bottle through the night. She has 2 day naps 1-1.5 hours in the morning and 1-2 hours in the afternoon. She goes down at 6pm, if she has a bottle through the night she'll sleep till 6 if not then up between 430/5.
It will pass. I have come to the conclusion also that not all kids sleep! 😆😆
