All Clearance Items are Extra Small sizing. These bibs were mistakenly made slightly smaller during production. Even though our suggested age is 0 to 4 months for these Extra Small bibs, they will very likely fit most babies outside of this age range (up to 24 months). If your baby is in that stage where he/she has a lot of extra cute baby fat, these bibs may fit snug around the neck until your baby becomes more active (crawling, walking, running). If your baby falls into this category, we suggest that you purchase our standard size bibs.
