Spending my sons 2nd birthday alone, as a single mum with no family. What do I do?

So my sons birthday is this sunday and I didn't realise it was getting so close!

I can't afford a present I don't drive or have a car and have no money. Everyone's working. I'm a single mum and have no friends so I'm wondering what I can do with my son to make the day a little more special than normal 😔

I feel like a let down because of it
