DS normally sleeps for about 1 cycle 30to 40 mins during the day then he will wake up screaming. I have been turning on white noise to resettle him and it seems to work. I wonder how many of u use this technique? Do they become dependent on it just like dummy? I only use this during the day as he catnaps a lot. He is all right at night, just waking up for his feed, every 3 to 4 hourly.
