The children's formula is safe (in my opinion) and needs to be measured according to your child's weight. I do hope you consider treating her, especially with the fact that she has chronic constipation. Poor sweetie. I wish the pediatric society would look into this with children, as my son ate dirty kitty litter as a baby, and what else do they put in their mouths???? I do hope you get health and healing for all of you before she has a lifetime of health issues. Will pray for you to have wisdom! (my kids did not have bad die off symptoms, because their detox systems in their bodies have not been bogged down by years of bad diet and chemicals)
