Any baby-led weaning mommy here? How to overcome the fear of LO choking since they are learning to gum the whole food ?

For a start, give smaller mouthful or pieces. Don't try to give food that requires more chewing till later stage when they are used to chewing food. Monitor and monitor. You must prepare yourself in what to do in case choking happens. For my baby, I steamed baby carrots which are v soft, to let her bite. Then small quantity of grainy porridge rice. The idea is to encourage some chewing. Once she mastered how to chew n swallow well, then I will intro other more food.
