Husbands little sister is staying with us this weekend...

So my husbands little sister is turning 14 soon and she’ll be a freshman in high school. Her hobbies consist of sitting on the couch all day on her phone and eating junk food and playing volleyball in her club.

She’s staying with us this weekend while his parents are out of town and I’m not sure how to keep her company, besides her phone. I’m 29 weeks pregnant so I don’t think volleyball would be a great idea for me to do right now.

We live in a apartment which has a pool and a sand volleyball court so I was thinking of swimming with her and letting her volleyball buddies come and play with her at the sand court.

My husband has to work all weekend so it will mostly be me and her. She’s staying with us tonight until Sunday but I want to do other things with her too.

Any ideas or suggestions that we could do?? We’re limited on funds so shopping wouldn’t be a thing for us to do. She’s also really quiet and stays to herself most the time.
