When it comes to the size, a standard measurement is till your baby’s abdomen. Many parents make the mistake of buying shorter bibs that reach their chest. This is okay only when you feed the baby. After they start learning to have meals on their own, there is bound to be more spillage. If the baby sits, this should easily reach their tummy. This way, it protects their clothes, even if it gets a little more messy than usual. Longer bibs are best. You can also wipe the food right off the bib before taking it off. This isn’t possible with shorter bibs and can result in staining their clothes.
