@Mystique Yay! Thanks for the good suggestion! 
When it comes to casting, some say it’s fine to cast for others, others say it’s not okay to cast for others, and others will say it all depends on the situation. Ultimately, whether or not you feel casting spells for someone else is okay will boil down to your personal magickal ethics.
No one should tell you what is right or wrong for you and your practice - it’s a valuable and important thing for every witch to explore for themselves 
Whatever you choose to do, I’m wishing you (and your son!) only the best, Dawn - blessed be!
