Help Ukrainian children

My aunt in Poland has taken in a family of 5 Ukrainians - a grandma, 2 moms and 2 little girls, aged 7 and 11.

I turn 11 this month. This birthday, I do not want gifts for myself. Instead, I want to help the girls who had to run away from Ukraine because of the war. I want to raise fund to get them books, toys, and warm clothes. I am lucky to have my friends around me. These girls aren't as lucky. Please help me help them.

Thank you for your generosity and kindness.
