The article stated she had an infant life jacket. Since we can all see she was able to put it on, then it was most definitely not an infant size. The msm lies at every turn.
I don’t know about aviation vests but in boating there are usually only three types: small, med and large. Would not be out of the realm for the media to get the jargon wrong. If she had a “small” its possible she still could have go it over her neck just not where the life vest is supposed to go which his lower on the body.
Allthis is speculation since none of us were there ever with the go pro photos you don’t get the full spectrum of being there.Eyewitness is always hard to beat.
