Is it a baby?

Yes, it looks like a baby. The mushy-ness of the new leaf is worrying. It looks like some fungal or bacterial infection has set in. Hopefully, someone more experienced with this will chime in. This might be a case where cutting below the level of the rot and applying hydrogen peroxide is warranted. I’d also make sure you wash your hand after touching the mushy part so you don’t spread it (if it is a pathogen).
