Was talking to a school yard Mum about when she weaned her (now 5 year old PFB) daughter. She used to cover the highchair tray with stuff like porridge or mashed aubergine or whatever, rub her daughters hands in it, help her daughter suck her hands, rub food around her mouth.
Seems utterly needless faff to me. I see no point in doing it except perhaps that it might be exciting/funny for the parent to watch. Seems too PFB to me, but each to their own.
If my DD is hungry, I feed her. With a spoon. She loves her food so much that there is rarely a single bit of mess. I often don't bother with a bib because everything goes in her mouth and is eaten.
If she's not hungry never happens then we leave what's left.
Usually she has a full portion of mashed whatever (fed by me), a full portion of mashed fruit or yoghurt (fed by me), then finger food of whatever we're having afterwards (which she is left with while I sort everyone else's dinners).
I'm evidently not fully on board with the BLW methods, but perfectly fine with that
