I have a none month old who just started with me and so far he has only eaten purees and bottles. His parents tried some puffs with him over the weekend and packed some for him, but he doesn't seem to know how to pick them up. He just looks at them and gets upset. I have nother nine month old who eats everything himself and has pretty much never eaten purees. I know each child is different, but any advice on how I can encourage this little guy to try picking up the food would be welcome
