A story about how a new baby's arrival impacts a family, told from the point of view of a delightfully unreliable narrator, a wildly imaginative 7 year old named Tim.
This movie contains 7 potentially triggering events.
The baby tries to get his brother to suck a pacifier and the boy says "no, you suck it," the baby responds, "no, you suck it" and so on back and forth. The brother ends up sucking on it after saying no multiple times.
Towards the end, Tim and the Baby wanna get rid of their "babysitter", so they make fake bright green vomit out of cereal and other ingredients. It gets in the babysitter's mouth and stuff. It's kinda gross, but it's a cartoon so it's all played for laughs.
The “babysitter” is a bad man disguised as a woman. I read somewhere else where a viewer warned that this could be considered transphobic or “man in a dress.”
