Signs of upping formula

This question is the bane of my existence 😅 my little guy will keep drinking until he spews it all up and very very rarely doesn't finish a bottle

I’ve always done it when my kids have been finishing most bottles in the day. We done this as my boys been on 5oz for a while and I’ve tried to up him a couple of times and then he’s hardly taken any so put it back down except his morning one has been 6 for weeks now as he sleeps through the night. Yesterday he was getting hungry after 2 hours and finishing bottles so we increased him to 6oz every feed and he’s taken to it this time and has finished every 6oz that we’ve given him now. If you up it and baby doesn’t want it, just go back down until they’re showing more signs of being hungry quicker or finishing most the bottles again and looking for more x

We just give more until she stops eating. Sometimes she'll have 180-200 at a time, but as you said sometimes it'll just be 60. They're supposed to know when to stop
