My son has them when he is EXTREMELY tired..they are crazy as well!! Sometimes like scared of the elephant in his room, and wants to get in the corner - very scary when your kid is acting like that! This homeopathic has SAVED us...
Homeopathic Stramonium. With a 6C does (low) my 5 YO stop having them within minutes of taking this. Also this can even be used for the younger kids at 6 months. Highly recommend!!!
