Judy Ann Santos is admittedly having separation anxiety now that her youngest daughter Luna has returned to school.

On Instagram, the actress shared photos of Luna's first day back in school after more than two years of remote learning due to COVID-19.

"First day of school for our little bunny.. first day for all of us after 2 1/2 years of online schooling … nakaka sepanx ng sobra!!" wrote Judy Ann.

"but.. I’m happy and excited for all the kids to be able to attend classes with a bit of normalcy. Thank you to all our hardworking teachers for doing everything to make this happen," she added. "Dear God, please bless, guide, protect and look over our children and teachers as we all move forward from this pandemic."

Aside from the actress, her husband Ryan Agoncillo and their son Lucho were also there to send Luna off to school.

For her first day, the couple prepared a special breakfast for Luna, along with a sweet note that read: "My dearest bunny, happy 1st day of school my love!! So proud and excited for you! We love you! Mom & Dad."

Both Lucho, 11, and Luna, 6, received their COVID-19 vaccines last February.
