erm, i think 19 mths old shldnt be still taking blended food already. shld start giving chunkier n more textured food from 1 yo onwards. if not, he will have issues learning to chew.
you can include noodles and pasta into his food list.
also can give him pancakes, waffles and sandwiches as snacks and breakfast.
IMO, try not to blend his food anymore and give it directly to him.
