I also plan to use my emergency fund for my child's needs, as he will start school in about a year, and I can use my emergency fund for future needs and beyond as much as possible without having to use Bitcoin prematurely.
I don't think is necessary to tamper with your emergency funds to cover your child expenses that's is about to start school . Since you're aware that your child needs will be coming up in a year time,then it is no longer an emergency situation. Emergency Situations are unplanned events or an unexpected occurrence. So likewise the Use of Emergency funds,it should be seen as a safe haven or safety nets where you can fall backs to when Real life Emergencies happens. However I think what you should be thinking of using to cover up your child future expenses is using your reserve and backup funds.i think your reserve and backup funds should be used to dealt with extra costs in regards to your child needs and not your Emergency funds.
