Thank you and congratulations to you. I am a new grandma too. It is the best. They touch the strings and their eyes light up.
Interesting note to your first lesson chords E and Am. I know you explained that the fingering you use are just 2. I know a “few” chords and use 3 fingers for those chords, so at first I was confused until I realized it did not matter. The exercise starts with the 4th and then 3rd string so the fact that I am holding down the extra string does not matter.
I know you can laugh but for me it was a little ah ha moment.
