I have purchased Healthy Times Puff yesterday. He likes to eat and show smiling face when he is "chewing" though he doesn't have any teeth now. But I think it's too small for a baby to eat by himself. I have to hold it for him to eat. It defeats the purpose of training him to take the food and eat by himself.
Today I have bought the 森永 baby biscuit. It was on sale at Seiyu Shatin (only $8.9). I have also bought another japanese brand rice cracker. I will let my baby try these two days.
