When to up Oz’s of formula

I’ve always done it when she is consistently draining the bottle and feeding every 2-2.5 hours. As long as they are getting their calories in during the day then they are okay to sleep long stretched at night is what I was told by the health visitor. My little girl sleeps through the night but had bottles every 3 hours in the day to make sure she gets her calories in

We always up his feeds when he's draining a bottle and then demanding more at 2.5hours. Currently starting transition to 7oz and he's starting to demand more sooner xxx

When they’re draining most bottles, still seem unsatisfied after feeds and start wanting another bottle less than 3 hours since the last one. My girls 14 weeks and I make 7oz bottles every 3 hours and she usually drinks at least 6 but sometimes 7. If she’s full she just won’t have anymore. At 10 weeks my girl was on 5oz every 3ish hours but after 12 weeks she definitely wanted more x
