Baby not finishing bottle

[Tabithalevi]

Hi, my baby was 12 weeks on Friday.. for the past 2 weeks I have noticed that she has not been finishing her bottles, i recently put her on 6oz increased from 5oz but she's leaving between 1-3 oz every feed... when she was on 5 oz she would typically finish her bottle almost every feed.

Hope this makes sense.. need some advice

Mine were mostly breastfed ar that age but they do go though phases when they're just less hungry/ start to be distracted by their environment. I wouldn't worry unless they don't seem alright in themselves, don't have regular wet and dirty nappies or stop putting on weight

Mine were bottle fed, found like you when I moved them up am oz or so they seemed to leave more. I didn’t worry, I would have of they left more. Chances are baby I’d getting fuller having less formula because it’s got more formula added to it. If that makes sense
