I feel like a horrible parent

So my son asked me today why Santa and I don’t get him as much as Santa and daddy does there. His dad gets him over 100gifts. His dad lives at home with his parents and has no bill. Well I live on my own, with no help so I can’t afford what his dad gets him. He asked if Santa can get him more this year. I also have another child and her birthday is in December with makes it harder.. ugh I wish I could do more 😭😢
