Oh dear...I'm sorry to hear that! I hope your little boy is well. Do you give him tea? Chamomile, fennel seeds, caraway and anise seeds help wonderfully and can also be given to a baby in tea form. It also helps a lot if you drink the tea yourself and consume it with milk.
If this happens frequently, he may be sensitive to it depending on what you have eaten. Onions, garlic, legumes, dairy products etc. Just observe...
I hope you can relax a bit and electricity is back to normal 🍀
