My 8 yr old son has ADHD and is medicated he stole 40 $ from me and has been lying about it I thought I was going nuts when the 40$ came up missing and 2 days later my son just finds 40 dollars not sure what to do I punish him by making him stand in the corner or taking his things away I'm really thinking about spanking him he has been spanked before for not behaving in school . Any inputs thank you for reading
