Those supervised visits with mommy apparently register as “terrifying” on the toddler distress scale, because Britney’s boys have been having nightmares ever since she came back into their lives. According to Page Six

Sean Preston has been sleeping in the same room as father Kevin Federline lately because he’s been having nightmares. Preston also cried for his dad at first when Britney picked them up. The boys are said to be confused when it comes to their mom, which is another reason why either Jamie Spears or a psychologist is present during the visits.

I’d say “confused” is an understatement. You can’t expect a kid to just black out the night mommy was strapped to a stretcher and hauled away. The wail of the sirens; the flashing blue lights; the steady drone of the choppers circling overhead while mommy screams from inside the bathroom — it’s practically Viet fucking Nam, for Chrissakes. Only instead of the man in the black pajamas, it’s a fat chick in a pink wig and British accent. That’s got Post Traumatic Stress Disorder written all over it.
