The Hamills are a very unique American family: Couple Dan and Michelle, son Jack, and twin sisters Cate and Cece are all little people! Jack starts Kindergarten, and Michelle worries if he is happy and fitting in with the average-sized kids.

The Hamills are gearing up for Halloween, and Michelle decides it's the perfect time to start new family traditions. On the big night, everyone dresses in costume- even Dan! Meanwhile, Michelle thinks son Jack is old enough to start doing chores.

Dan builds a small play set for Jack when he notices his son's struggles to keep up with friends on the playground, but Michelle worries about Jack playing soccer with older and bigger kids.

It's the Hamills' 7th anniversary and Dan's gift for Michelle misses the mark. To make matters even less romantic, it's time to potty train Cece and Cate! Can Michelle figure out a way to add romance to her marriage and get these girls out of diapers?

Michelle rarely ventures outside her hometown because everyone knows her family and she feels safe in her bubble. Worried this is limiting the kids' views of the outside world, Dan and Michelle branch out and take their first family trip to nearby D.C.

Twins Cece and Cate are turning 3! To celebrate, Michelle plans an elaborate birthday party while Dan attempts to build his daughters new big girl beds. With less than a week to get ready, it's a race to make everything perfect for the girls' big day.

Michelle takes on the challenge of cooking the Thanksgiving turkey for the first time! Meanwhile, the Hamills are quickly outgrowing their rented townhouse and consider buying their own home. The parents also try to help Jack find a new winter sport.

It's nearly Christmastime, and the Hamills take a fun winter wonderland vacation to the Pocono Mountains! Michelle hopes to fill the season with new memorable traditions, and she hosts a holiday party for the family's little people friends.
