Elderly, disabled mum broke her arm in Nov. Since then a family member has stayed overnight to help, with carers coming for morning and bedtime care. We are just starting to move forward, leaving just carers to do the morning and bedtime duties and need to sort a hot early morning coffee so that she can take her meds. We have tried a coffee machine but she can’t manage it. Any advice for a flask or jug that keeps drinks hot for up to 12 hours. She can’t manage a screw top.
