Hi, Thanks for the query.
I think in this case you should not fear and due to cold
( may be drugs use) child may have 3-4 motions and due to these motions child get up in the early morning and became hungry.
Type 2 diabetes
is hereditary disease and inn your's child it seems that such thing are not possible .
Still you are in doubt so please get the blood examination of little one .
Also pl get an ultrasound
of the child to rule out any pathology in pancreas
gland ( diabetic controller ) .
99% chances are the child didn't have any problem , still you can visit a physician and get all examinations done .
Good luck. Dr. HET
