Help Sienna to help the homeless

Hello my name is Sienna, I am 6. I have been speaking to my mummy about how it makes me sad that the homeless must be very cold outside, and I wanted to donate Teddy bears to them but my mummy explained that as kind andthoughtful as that is, that there will be better ways to help them. So I would like to raise money to buy them warm blankets and sleeping bags.

If you are able to help me I would be very happy. Thank you.
