Is English her first language?Statement Analysts would have something to say about how she calls the seat of the car where she was changing the baby a "chair" and says she woke up "on the floor" instead of on the ground.
I got the sense it's not. Personally I would give someone a pass for poor word-choices when/if it's not their first language. But I would still pay attention to things like her providing justifications for her actions and things that won't help solve the case (I smelled he needed a diaper change so I said okay we'll change you/I was getting his diapers out), and those that seem designed to influence the audience into thinking she's a good parent (he was a happy baby) and missing important details, like actually being hit.
IMO
