Kids are more resilient than you know and what's seems as a problem now will not even be a thought in the future. Just be in their lives and be a well spring of love and guidance. We cannot control the feelings we have just our thoughts of those feelings, this is where your intellectual intelligence puts into context those emotions and the separation of self of who you are and how your brain processes your life. "Don't worry, be happy."
You should show show them removal of the lower branches at flowering "Lollypopping", they can try it on a couple to test. They'll be more than happy with the results. Black strap molasses, compost teas, are the using high phosphorus bat gauno at flowering? Help them out while your there lol.
