What could be an effective approach for a repeated cross-sectional design with less than 10 data points?

Good day!

I am working on a dataset related to child-nutrition, and I was able to obtain individual-level data on BMI, Height-for-age and weight-for-age of school-aged children between 2016-2021 only. I have watched a lecture on dealing with repeated cross-sectional (RCS) design using ARFIMA-MLM, however, it requires at least 50 data points for the ARFIMA-MLM model. What could be the alternative approach to dealing with RCS data?

Thank you so much!
