my 1yr old had neonatal hypoglyciemia due to hyperinsulinsim when he was born, aparently this is quite rare, and he would most likely grow out of it. i havent needed to test his bloodsugars for a while but lately when he is playing his sweat smells like vinegar and his urine is strong and he drinks so much water. sometimes he is really hard to focus and i wonder is these are signs of low or high blood sugars?
