Continuity mistake: After Sam's dad leaves, Sam gets out of bed, grabs her poncho and shoes and puts a bag over her shoulder. She puts her poncho and shoes out through the curtains twice, and as she climbs through and jumps out of the window, the bag has vanished from her shoulder. (00:21:35)
Continuity mistake: When Chrissy, Teeny and Sam are standing near the barbecue and table of food talking, they turn to walk over to the foldout chairs and swings. As they turn around you can see by the tree are two flowery foldout chairs next to each other. But in the next shot when they walk over there, there's now a small flowery footstool in between the two chairs. (00:08:30)
Continuity mistake: When the girls go to visit Sam's grandma, she has only two glasses of lemonade ready. When she sees the other girls, she says 'Let's find some more glasses.' She's away for about five seconds and comes back with five full glasses. Are we expected to believe she got to the kitchen, got the three extra glasses and filled them with lemonade all in five seconds?
