As a cheaper alternative to a full Christmas outfit how about Baby’s First Christmas Bib. A Christmas Bib on little bubba can brighten up the most busiest of Christmas days and have a great multifunction purpose of dressing up a plain outfit and catching those drops of baby food.
You can decide if you want one that goes on with a tie neck, a velcro or snapback neck or one that goes completely over the babies head. For older babies, you might consider the firmer silicon/plastic food catching bibs.
