Kate Gosselin said she was a “proud mom” as she posted a photo of her kids getting ready for their first day of school — but two of her eight children were missing from the shot.

“Feels like school never ended…and they’re already back!” she captioned the shot of 17-year-old twins Mady and Cara, and four of her six 14-year-old septuplets, Leah, Alexis, Joel and Aaden.
