you can watch TV via the internet. your local library might have access to streaming hoopla and Acorn TV for example. There will be things your grandaughter can watch.
I use both hoopla and acorn TV via library membership and have slow internet access.
I can live stream. I'd just have to sign up for some content. We do watch some YouTube movies bit not often. But I am usually so tired by the time I finish with the farm chores and getting my granddaughter her bath, fed and ready for bed, that I end up reading stories to her in the evening. She picks up so many more words and concepts from reading to her instead of watching TV. It's a good time for us to bond too.
As a two year old, she is the focus of my attention. My needs and interests, except for the cows, take a back seat to her needs. Hopefully, it will get better as she grows older. She'll be three in May. She also brings the crud home from her daycare school that has turned into two bouts of pneumonia for me. I should have been in the hospital but I have no one to watch her. So it is what it is.
