my little one is two and half month now,and he seems like to eat his hands very much and always put them into his mouth.My husband try to stop him by beating his hands.Every time he sucks,he beat his hands.He say after several times he will start to realise that its a bad habbit to do so.Just like train a dog.Is it a good way to train him in this way?And should we stop him?because i heard that sucking finger is the way that baby comfort himself leh.
