hi all. for 4 nights running my 6 week old ds has slept pretty well 'til around 4 / 4:30 am (waking once for a feed around 2 am), then has woken up and grizzled/cried. a bit worried because it's a cry that i haven't heard before - he seems to be really unhappy. feeding/changing/winding/snuggling don't seem to help. wondered if anyone else has had this pattern? thought maybe he was struggling to pass wind or fill his nappy, but there hasn't been a noticeable pattern in terms of what has followed (i.e. a filled nappy!).
