Always best to use HMRC's actual guidance and if something is not specifically mentioned in the guidance, such as feeding sets, then assume it doesn't apply to whatever Notice you are reading.
Young children's clothing and footwear (VAT Notice 714) - GOV.UK
Is a bowl, a plate, a cup and cutlery the same as a bib?
The zero rating is specifically for children's clothing and bibs are deemed to be clothing as they are worn by babies almost all the time and HMRC accept plastic bibs can still be clothing as they too are worn on the body.
Do babies wear spoons, cups and forks as clothing? Not intentionally!
Sounds like a single supply made up of a mixture of VAT rates, you may need to decide what the dominant supply is, out of your 6 items only the bib is zero rated, the rest are standard rated.
If you take a Christmas hamper it consists of zero rated foods and standard rated alcohol or goods like the basket itself, maybe a chopping board or some cheese knives, so you have to apportion the VAT accordingly, you can't just say the whole hamper is zero rated because there is a single packet of biscuits in the contents.
Worth reading this link and its subsequent pages which shed light as to how HMRC thinks/approaches this topic.
