This has likely been asked so many times but I'm wondering what age and how did you stop.
My DS has one when he sleeps. He doesn't have it when he's awake. He'll be 2 in April.
He also has a comforter toy which he sleeps with. Last night he went off to bed without the dummy but woke during the night unsettled and I ended up giving him the dummy (we all need sleep!).
I wonder if I'm doing it too soon? Any ideas please. I don't think it's causing him any issues so may be he can keep it for a while longer.
