Poetry and little ones

We started the Poetry Memorization program with our 5 year-old, and are up to 14th poem in Level 1. It usually takes about 2-3 days of passive listening to a poem on the CD 3-5 times in one sitting (one session per day). My daughter then begins practicing on her own, but doesn't listen at a volume I can hear so she can surprise me by the end of the week.

I've found that using a chunk method (whole poem stored as a unit) instead of line per line or stanza is a lot faster. I noticed the difference in speed when the first time I introduced just listening to one stanza at a time to memorize for “After the Party” (because I thought it'd be too difficult to memorize all at once). It took her a lot longer using this method, so I went back to chunking method. She still gets stuck occasionally on this same poem, yet others, which are longer, are smoothly stored to perfection.

I understand that when one is considering Suzuki method, there is a listening stage before any attempts at lessons begin. I partially applied this by not expecting any output initially. Even my little 3 year-old boy is about on track with the older child (with some distorted pronunciation expected of his age in articulation).
