Near the beginning of the movie when Skeeter goes to his sister's house for her daughter Bobbi's birthday, Skeeter mistakes Patrick to be Bobbi, presumably due to the "boyish" sounding name. However when Wendy's best friend Jill shows up and is talking to Skeeter outside of the house, the present she has with her is wrapped in very "boyish" wrapping paper with basketballs and footballs all over it.
In the scene where Skeeter first spends the night with the kids, Jill and the kids are making signs. On the sign that Bobbi is working on first the C is not colored in. A little while later the C is almost completely finished; a few seconds later the C is just started, and a few seconds later it is just a little bit less colored in than just a second before.
When Bugsy is looking at Kendall from inside his cage, it is clear that he is looking at him from an opening in the cage and that both eyes fit in the opening and his sight is unhindered. But when the camera is angled from Bugsy's point of view, the cage is hindering his view.
On the first night that Skeeter keeps the kids, when he is saying "goodnight" and turns out the lights, we see Bobby roll over onto her stomach. However, in the next shot we see her on her back (shrugging her shoulders).
The goof items below may give away important plot points.
In medieval times, Skeeter dubs Bobbi "Mistress Stinky" and Patrick "Master Smelly". Toward the film's end, shortly after Tricia Sparks approaches Patrick, Skeeter mistakenly refers to Patrick as "Master Stinky."
At the end when Tricia Sparks professes her love for Patrick, she has her hair in pigtails. As the camera switches from a frontal shot to an over-the-shoulder one, her left pigtail jumps from behind her shoulder to in front of it and back again.
