If I’ve understood this correctly, Lizzy’s 3 month old grandchild was taken to the (dirty) house of an alcoholic for the alcoholic’s 14 year old daughter to babysit, alone, whilst Lizzy’s daughter-in-law went out for five hours. The baby is breastfed but the 14 year old was left with ‘a’ bottle to give it. Really only one bottle? No I don’t consider it is acceptable to leave a baby alone with this young girl or in these surroundings. Why the 14 year year old was chosen, and why at her house rather than the daughter-in-law’s, we don’t know. Perhaps Lizzy could explain that (is the 14 year old related to the daughter-in-law or is the alcoholic daughter-in-law’s friend (Lizzy has presumably been inside the house to know it is dirty), also whether she thinks it might happen again.
