My DS (nearly 1) has used dummy on and off since birth though only during the day and never for sleeping. Since a visit to grandparents a couple of weeks ago when we gave him a dummy to help him settle in the middle of the night we have given it to him at home, too, and he seems to sleep longer and better (less wake ups) with it. Without a dummy he will only sleep 9-10 hours a night, with a dummy 12. He seems happier and more rested in the morning and wakes up with a smile on his face rather than crying. Given that we have managed nearly a year without a dummy and I know that he can go to sleep perfectly well without it, should I take it off him or keep on using it as it seems to ensure better sleep for him? Everything in me says ditch the dummy before it's too late but on the other hand DS doesn't nap very well during the day and someone said that 9-10 hours isn't enough sleep for a 1 year old so if I can get 12 hours with a dummy, is it worth it?
