Does this sound rude?

I’m a daycare teacher for 2 year olds and we’re having a party next week. My mom said this message seemed a little rude so I didn’t want to send it just yet. Does it seem like it is? And if so what should I change?

“Hey parents, I know I spoke to some of you already but just as a reminder we will be having a party on Tuesday, October 29th. Lunch will be provided for the kids. We also will be painting pumpkins and doing a candy hunt and a couple of other activities with the kids. Feel free to also dress them up in costumes you’d like.” I also wanted to add a part about if they wanted to bring something or the kids then they just bring a small pack of candy.
