Wow!Almost anything!: There is a huge range of normal for 12-year old boys...On the cusp of puberty for some, late for others. Go to cdc website @ www.Cdc.Gov; type 'growth charts' in the search box at the right upper corner of this webpage; click thru the menus until you see boys charts geared for age12. Plot your son. Hopefully he is good! if in doubt, talk with your pediatrician or nutritionist for more.
