>If you're concerned, ask about it – a testimonial, note, etc. might be more within her comfort zone.

I don't really care enough to ask(email) about it but it is really unusual to see a product targeted for children being marketed by a flirtatious woman (or mom?) instead of showing actual kids using it. I would find it similarly unusual if I were to see an ad on TV for a kid's toy without any kids in them.

She mentioned future kids. Perhaps she didn't want to exploit her friends kids for marketing purposes.

Still though, I'm curious if she's done any product-market fit?

The difference is that most of the TV ads you see are produced by media professionals with 6+-figure budgets. I thought the video was understandable for someone who isn't a professional video producer and is trying to get a project off the group on a shoe-string budget.
