Day time as well as night?
My dd is almost 1 and has never been easy to get to sleep. We go through periods where she gets quite good at night sleep and then a growth spurt hits or new teeth appear or she learns a new skill and then we start right back at the beginning. I'm sure she's chronically overtired, she usually has a decent amount of sleep during the day but only takes those nap once she is already exhausted and only when i actively do something to make it happen. I've tried to put her in her cot but that just results in her becoming hysterical.
Anyway, no point to this really other than to get it off my chest. I dream of the day she says 'mummy, I'm tired, can i go for a sleep?'. It will happen, one day, it really will
