I had issues too but I find that if you put the babies bib on, give the baby a sip of the milk ( there are 3 sips) afterwards go to toys and give the baby the rattle or the toy keys. That will give that percentage of 100. The toys give 25 -30 percent that I can assume is the babies hunger or cooperation to eat.so basically put on the babies bib , then 1 sip of bottle, give either the rattle or keys then give spoon. Do that repetition 3 times or so. Hope that helps
