Sure! Here’s a polite way to ask your friend's mom:
Subject: Sleepover Invitation
Hi [Friend's Mom's Name],
I hope you’re doing well! I wanted to ask if it would be alright for Mahlako to come over for a sleepover this Friday. We’d love to spend some time together!
Please let me know if that works for you.
Thank you!
Best,
[Your Name]
