Companion for Daniela while I'm at work, São Paulo

I'm Sérgio, and I look after my mother at home in São Paulo. Daniela has a weak heart and should not be alone for long stretches. I work until six, and the gap on Tuesday and Thursday afternoons is the hardest part of my week. What I need is someone calm and reliable to be in the house from about 1pm until 5.30. Mostly that means company, a cup of tea, lunch and a short walk if the weather is kind. No lifting and no medical care. Daniela loves old films and will talk your ear off about it. I'm home before dark and will always leave the phone numbers of the doctor and a neighbor. I'd like to meet you first with Daniela present, and I'm happy to give a reference from our doctor's office. If you have done care work before, wonderful, but kindness matters more. If this is something you could do, please write to me through the offer button.
