HJ sweety it's not your fault at all. Babies have a certain time at day/night were you won't be able to settle them and I know it's distressing for you as you think you should be able to calm them but they will get better with time, it's hard been a mummy but as the saying goes "this too shall pass" and it will hunny, just give it time. As for the clots, if they are as big as your palm then I would be going and seeing the dr/or hospital as you may have some retained palcenta. Big
