The sheet is blank and you tell your guests to fill in the boxes with words associated with babies, pregnancy etc. You can download a list from the internet and call out the word (bib, diaper, girl, pacifier etc.) until someone has 5 in a row across, up/down or diagonal. As you call out words the guests use a sticker to cover up the word and the first to yell bingo is your winner. You can play multiple games so be sure to have LOTS of words.
