Harley has slept in his own bed in our bedroom from day 3.
He is now 8 months and sleeps in three or four different places in our bedrdoom (including in his bed) and on the landing during the night - but not on our bed! I get really grumpy when my 'space' is invaded, even by the kids when they were small, I just cant cope when I haven't had a proper nights sleep. Harley is allowed to jump up for a cuddle first thing in the morning but jumps off again after 10-15 mins, think he gets too hot. This arrangement works for us, but then I guess we all have different preferences so good luck with whatever you decide.
