This will be my 5th night BWing and each night, my 5 mth old DS has mantra-ed for some time. LAst night he started around 2am - I left him and within 15 mins he was quiet and I assume asleep. Then at around 4am he started again - I left him, but an hour later he wass still doing it. I went in at the point to try and settle him, but ended up feeding him. At no point was he really crying, but I felt that he needed my help to get him over the getting back to sleep hump. Should I have left him?
