The key is don't panic! Baby led weaning will often cause your baby to gag because a piece of food triggers their gag reflex and they're not expecting it. Make sure you are trained in baby CPR just in case your baby is truly choking (this is very rare though). Gagging just means your baby is attempting to chew the food and move it around in their mouth - which is a good thing! If you are concerned about gagging, I recommend mashing the foods for your baby to pick up and eat, or offering purees first.
