Hello everyone! We've been trying to eat buckwheat porridge for three days now. It all comes out, gets spit back up. Here's the question: Can we switch to another kind of porridge or just remove it for a while? And one more question: Is vegetable puree too early? For example, cabbage, potatoes, carrots. Or Carrots, potatoes, broccoli, cucumbers?
