Fussy eater/ not drinking lots

My first only took tiny amounts of milk and gave it up as soon as possible during weaning. She just hated milk I think 😅 Loves yogurt though! She caught up on weight massively when weaning, so I'd said don't sweat it atm. There's nothing you can really do to make them drink more than they want x

My baby is 13 weeks and we were having the say issue. I spoke to my sister in law who is a midwife and she said try and do 4hours between feeds as 3 hours is too much.
Started that yesterday and every bottle she’s had she has finished x

how many oz is she taking in those 4 hours please? My little girl will sometimes go the longer stretch but still only drinks the same amount, she goes quite a while through the night over 6hrs most nights and will still not finish the bottle in a morning

She has 5oz. She doesn’t finish all of them sometimes. She’s sleeping 8-10 hours each night and the first bottle in the morning she sometimes doesn’t finish either x
