maybe try other cannabis-based treatments for pain control? that might help. There are some herbal teas that induce the body’s healing properties as well, but I’d recommend taking that along with other methods not on its own. Also, make sure it doesn’t reduce the effectiveness of other pain medications first.
I think your child is dealing with stress from an overactive imagination. I’d consider giving them something that comforts them before sleeping, like a “monster repellent spray” that’s just filled with lavender and sleep-inducing essential oils!
I usually buy candles and aromatic steamers fo the house, and I fill them with essential oils and it makes the house smell sooo nice! This really works, and if you want to know more about it I’ll leave a link for you here.
