Two websites offering boy-themed printable games for baby showers are frugalfanatic.com and printmybabyshower.com. Each of these sites also contains helpful ideas and tips for hosting a baby shower.
At frugalfanatic.com, you can print word searches and scrambles, bingo, nursery rhyme games and the "The Price is Right" game with boy-themed colors and backgrounds. The nursery rhyme game requires guests to fill in the missing word from popular nursery rhyme lines. "The Price is Right" calls for guests to estimate the cost of certain baby items.
Printmybabyshower.com offers printable games with a number of boy themes from which to choose, including animals, cowboys, baseball and mustaches. In addition to the printable games, there are coordinating invitations and decorations.
