Diapers and Blow-outs

Audrey • baby #1 born Oct. 2018, baby #2 born Aug. 2020

Today by daughter had a blow-out but in the front, top of the diaper. She was sitting in a bouncer at the time so this seems odd to me. Did I make a mistake when choosing diapers or is it time to size up?

She was wearing Huggies Snug and Dry size 2.
