Benefits for my child with Down Syndrome?

Is there anything I can get help on for my baby girl with down syndrome?

For example, can we talk to someone about finding a home for us a family? We live in a family members room and she doesn’t have space to move around or truly grow. We’re always in this little space. Three people in one room. Would she be considered handicapped? For a handicap apartment/home? Can I talk to someone about this?

What about transportation? Is there any way we can get transportation for appointments? Cheaper train/bus/taxi (uber) prices for her?

We don’t have a car so we take Uber’s everywhere and spend so much on just that, which makes it hard to buy her things as well.

I guess let me know what I can get help on.....

There’s so much out there but since I’m a first time mommy and we also didn’t know our baby was going to have down syndrome (we found out the day she was born), were honestly so lost and just need more information and we’d love to hear from people who also have children with down syndrome.
