£0 remaining for a large play cube

Mum is a single parent to her two children, a daughter aged 3 and a son, who is 3 months old. Mum has moved a lot due to domestic abuse, and she struggles financially. There is a very small back garden and the children don't have many toys. Mum struggles with her mental health and her daughter can really struggle on public transport or in play areas due to the noise. Therefore the children don't get out very much and would really benefit from having a play cube they can use either inside or outside. Thank you.
