Ok so dd isn't a preteen just yet she's only 9 . Ds is 17mths . Currently ds is in his cot in our room . He goes down great at night falls asleep mostly no bother . But he wakes during the night for hours . Dh and I are absolutely knackered 
Anyway . I don't know what to do to get ds to sleep better at night but I know I need to do something . Here are some solutions I have thought of :
- Take the bars off his cot but keep him in our room
- Put him in with dd in his cot
- Put him in with dd in the junior bed
- Put him in with dd straight into a single bed
I really don't know what the best way forward is
