We were having a hard time soothing our CHRISTmas Eve baby. My lovely wife hooked him up with a drop of Copaiba & this was him just moments after. We're not doctors or anything & we'd never give medical advice. I does look like he's expressing the relief he's feeling due to the oil rub. It's no matter, he's way too cute for catching the teething blues anyhow. Happy Passover Y'all!!!
