How to sleep train

Mine was a success . I only started when he was 10 months old . He would usually get cranky and fussy , because we did not have a routine before this . Babies will cry more when they are over tired . Then I thought I should start . I placed my baby in the cot at 8pm . Dim the light and switch on some white noise . I told him it's time to sleep . I also pat him and read him a bedtime story . He took almost 2 hours to toss and turn . But I did not gave up . I kept on patting him , turn off the lights and pretend that I was sleeping too (close my eyes) , and eventually he slept . I did this for 2 weeks . After 2 weeks , I try putting him on his cot and after reading him a book , he sleeps on his own . Now he sleeps 12 hours at night . The same thing goes for afternoon nap time . If he insist to sleep , I just lie down beside him and pretend I am sleeping too . It works ! U try , and update us
