I think the pics are beautiful. But for advertizing purposes, I'd stage it, perhaps by adding some props like candles, towels, maybe a glass of wine and make it a more spa like background. I don't see any product in the pics either. And not enough lather if your selling soap.
The baby is too cute for words, how about covering her with more bubbles and a shot with just her. The picture as is, looks too personal for an ad campaign. More for a family photo album imo. She looks young enough to still fit in a baby bath or even a sink. That may give you a better shot. If that baby cant sell soap with a face like that, I don't know who can
Another thought is to have the Mom dressed in a white bath robe (spa like) bathing the baby, looking relaxed after using your products. Try to sell a "story".
Just my opinion, you did mention we should be honest.
