 My son was born premature. He was lagging behind a little bit when I put him into daycare and could see the comparison because he's my only child. I started doing the full work for myself. And then I noticed his cognitive was enhancing. His motor skills were even improving. And I thought, but there's gotta be a correlation when I started doing the research. I've seen more, absolutely it was. But now can talk intelligently. My mother, his grandmother, says to me all the time, I cannot believe he's only three because of the conversations he can have. His ability to retain information and then relay it to adults is really incredible. And so I'm very interested to follow this along because he literally feels the calming effect of the calls and will ask me to go retrieve them when he's trying to get rested and relaxed. This is definitely the only thing that's changed in our routine and lives. This has to be what is making this effective. And so it absolutely isn't, plan to continue it.
