Am I sabotaging good habits?

I cuddle my child to sleep. I keep telling myself, it'll just be for now...he'll eventually grow out of it and not want me anymore.  But sometimes, like last night for instance - when he got out of his bed 3 times, I wonder if I'm just creating a bad habit.  Like, now he needs me to be there when he falls asleep, or he can't fall asleep? He can sleep in his own bed, sure.  But am I sabotaging good habits by letting him in my bed in the middle of the night?
