Try this, try that, try the other - everyone has a diff recommendation as to which bottle parents should try, sometimes parents end up buying them all! Baby should be able to use any bottle - yes even the very wide neck! This is what gets their masseter muscles working. If they can’t - why? What baby is doing with their mouth, lips, tongue, neck, shoulders, body all impact / and if appropriate what they’re doing to compensate. All these factors influence which bottles MIGHT work better in the meantime - but just because x bottle worked for the movements their baby was dojng, doesn’t mean it will work for yours.
