Am I wrong for this

So my SO was supposed to be off the next 3 days. But he wants to go in tomorrow.. tomorrow I have a little get together planned and I’m gunna make some food and gift swap with some family friends we won’t see on Christmas eve or Christmas. Is it wrong that I told my SO I need his help. We have a shit ton of laundry and have to make food and wrap presents for other people on top of manage a 2 year old. I am only one person, and I feel like I need help.
