Is BO a sign of puberty? You all know I have been really worried about difficult child. As of December, full physical and blood work. No signs of puberty at age 14. He has been so very tired lately and I was hoping nothing was wrong. He normally isn't one that sleeps in. Up by 9. Last night, omg - he KNEW he smelled, kept saying, smell me, come on smell me - smells like onions!!!!. difficult child was never a smelly kid. Although I am afraid of the coming years, I feel so bad that he is so small compared to all the other High School kids. Short and putting on weight. 40 pounds in the past year without growing any taller.
