Just watching it now. The only time she shows animation is when she is reading letters from the boyfriend.
She isn't guilty of the baby's injuries.but she IS guilty of minimising the risks he posed to that baby and also of being in utter denial about the events which led up to the phone call to 101.
She will lose all future babies too unless she really addresses this and acknowledges her mistakes. Continuing to see her boyfriend and getting pregnant with a second baby while the first baby was so gravely injured and he was being accused of that shows naivety behind belief.
