Help - my son is just 1 and think he has started to have tantrums, every morning when he wakes up he is inconsolable, hysterical and screaming, seems lifeless and sleepy aswell, (even after 12 hours sleep) he comes round after his breakfast and seems fine then, this also seems to happen mid afternoon around 02.30, think it might be tantrums, but also could be another problem, as was thinking low blood sugar levels, after i have given him food he then seems fine, took him to the doctors and not much use, as they said he had a cold, got another appointment this week, anyone any advice !!
