Dress up as the characters from this classic children's series—your mother will not mind at all if you do. In fact, she's probably the one coordinating this family affair. For an instantly adorable group idea, get the kids matching Thing One and Thing Two costumes. Then, dress up Dad as the mischievous Cat in the Hat himself. All Mom needs is a smart work dress to play the role of the unsuspecting mother who was out for the day. If it's your first Halloween as a parent, you'll go gaga over these sweet mommy-and-baby Halloween costume ideas.

Taco Tuesday with all the fixings

Tacos make everything better...but who knew that they could also make everything cuter? While anyone can take on the roles of taco, avocado, and hot sauce, of course, the avocado is a perfect option for expectant moms. Fashion the fruit out of cardboard, paint it two shades of green, and cut out holes to accommodate your face and baby belly. Grab a festive taco costume for your partner and a Sriracha chili sauce tee and green cap for your little one, and you're all set for a fiesta!
