Where can I read about baby-led weaning? Who has tried self-feeding BLW? I've been giving my child mashed zucchini from a spoon, I don't know what weaning is for me, it's something unknown, I don't know how to start correctly. They write that after vegetables you should give fruits, then porridge. How do I give porridge to my child? Can I make rice porridge myself? ? And how do I feed a baby?
