When you notice something hindering the baby’s airway and suffocating, the best thing is to gently start removing the hindrance without harming the baby. Don’t yank at anything, for it could result in something worse happening. Try to calmly pull the thing carefully so they can breathe and then put them in an upright position to make it easier for them to breathe, and so they can get as much oxygen as possible. If you see the situation getting worse, you should consider doing mouth-to-mouth.
