Addicted to Puffs

Okay, so we have a problem. The babies have been sick these last few days (cold/cough/diarrhea), so maybe that is it, but I have a feeling that it may be more than that. Claire is addicted to Gerber Puffs. Many of you may not know what these are, so I have included a picture. They look like little star cereal pieces, and they have different flavors (she likes banana especially). They dissolve in your mouth, so they are great finger foods. Claire is very good with eating these (and all finger foods), but now she is on strike and won't eat anything else but puffs! The only way we can get her to is to sneak in other food with the puffs...

Jack, on the other hand, refuses to eat any finger foods unless we put it in his mouth for him. He can pick it up, but he won't put it in his mouth. Nick was trying to teach him what to do tonight, and he started screaming when we would try to guide his hand with the puff in it towards his mouth. I don't get it...the boy can walk but can't feed himself. I don't know what we are going to do with him when he has to be off jar food...
