I'm now trying to give him something easy to pick up for self feeding. For example, cut carrot into 1/4" pieces, put rice into small group on his bowl or plate ... just hope he can pick up the food by his fork easily, then eat more.
I found that the "baby plastic spoon" is pretty thick (I think is safety issue ... not that easy to hurt their mouth), but sometimes isn't easier for baby to make food "drop" into the spoon. However, those adult plastic spoon (those for take away/to go food) is alot thinner, and make baby self feeding become successful ... I saw that Matthew could have food into the spoon easily.
