In the words of Catherine Tate, I DUNNO! Just sharing what I did - remember I never knew nuffink about BLW so just sharing what worked for us. Aph never sucked food, always ate it. Maybe she was just a Born to Chew baby. IMO food/weaning should be fun so if sharing it on your finger works then why not? (obv not holding their nose and shoving it down their gob).
