Companion for Nova while I'm at work, Allentown

I'm Leah, and I look after my mother at home in Allentown. Nova has a weak heart and should not be alone for long stretches. I work early shifts, 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 2pm 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. Nova loves gardening 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 Nova present, and I'm happy to give a reference from my employer. If you have done care work before, wonderful, but kindness matters more. Thank you. A few hours from you would make a real difference to our week.
