Hi Kuraiza Do you think he could have reflux? A baby with reflux will act the way Jude seems to be acting, with the constant crying and not sleeping well and nightly wakeups and wanting to be upright all the time and from the sound of it he isn't gaining a great deal of weight, which can happen in some reflux babies. Babys with Reflux can be a bit confusing in that they seem like they are hungry, but really they aren't. Have you tried any of the reflux/ colic meds like Infants friend, Brauer's or infant gaviscon? Is he a spewy baby? Is he content for any period of time after a feed at all? I think maybe you should take him to your GP or Paed for a check up and see where to go from there because I don't think this is a sleep issue that will be solved by going to a sleep school - the wont help you with any underlying issues, only give you tools to help him sleep (which can often involve crying) and many Mums come away feeling like they've learnt nothing at all that has helped.

I really think that there is something else going on with him - maybe even seeing an osteopath or chiro for him may help too - how was his birth? Do you think that it was a bit rough on him that could be affecting him?
