If I read one more article about how babies settle their sleep patterns at 3 months ill throw my computer at the wall. My DS is 13 weeks and since he was born has been on a four hour routine during the day, then feeding at 9pm followed by about 5 or 6am. (From 5 weeks. Previously he'd wake at 3 then 7) All of a sudden he is feeding 2.5 to 3 hourly during the day and waking up 4 hourly at night. Big feeds too. I'm worried its my milk supply because I'm EBF. Does anyone have this situation? Does it last? Been about a week.
