We are moving along pretty [well] and she already knew a lot of sounds before we started, but I’m not sure how to introduce the “ch” sounds or the “bl” sounds. What do I need to do?

Thanks for writing. “Ch” is what we call a digraph, and “bl” is a blend. These are fairly advanced reading concepts. If your daughter is reading on an advanced first grade or beginning second grade level, then these are great concepts to introduce.  If she is a beginning reader, now is not the time. Phonetic reading skills need to be well established and a strong reading foundation needs to be in place. Afterward, vowels are discussed, long vowels are introduced, and then blends and digraphs. You didn’t mention what her reading level is, so I’m not sure how to direct you. But if she’s a beginning reader—hold off on the blends and digraphs. They will come a bit later.
