Hello everyone! We started introducing solids, we're already eating broccoli, cauliflower, zucchini, squash, carrots, rice porridge, apples, bananas, and grapes through a blender. So, should we continue feeding them in a circle like this? Or introduce new products like canned meat? Or wait until 7-8-9 months, not rushing anything? Our pediatrician says let's give them juices and cookies (well, I'm actually shocked by her advice).
