When Dr. House says that he is performing a delivery in March, another doctor claims that March is "five months from now;" however, earlier when House audiotapes an autopsy on the Chen-Lupino baby, he says "...December 2004". March is THREE months from December.

During the autopsy, House states the time of death was on December 2, 2004. However, shortly thereafter the Hartig mother's blood vials show a date of admission of December 14, 2004.

Towards the end of the episode, as Dr. Cameron watches the family leave the hospital, the father exits the elevator holding some flowers. The scene cuts to slow-motion, and the flowers are now held by the person pushing the mother in the wheelchair.

One of the infants is stated to have a blood pressure of 80/40 and that it's dangerously low. In fact, this is well within standard range for a newborn.

When making a list of viruses possibly causing the infection, Foreman asserts that the entirety of the TORCH group of viruses can be ruled out. TORCH is then written in the "no" column. Shortly after, Chase suggests CMV (cytomegalovirus) as a possibility and House adds it to the "yes" column; however, the "C" in TORCH stands for Cytomegalovirus, meaning it was both ruled out and accepted as a possibility. An actual doctor would know what the TORCH acronym stands for and, therefore, would not make this mistake.

When making a list of viruses possibly causing the infection, it is suggested that one test can be done on one vial of blood. On one tube quite a lot of tests are possible, so drawing eight tubes for eight tests is really unnecessary.

When making a list of possible viruses causing the infection, Foreman mentions toxoplasmosis, which is caused by a parasite, not a virus.

While generating a list of possible viruses that are causing the disease in the newborns, Wilson reports that ribavirin, the first-line antiviral for respiratory syncytial virus (RSV), was ineffective, which should rule out RSV as the likely cause of the present illness, but Cuddy eliminates herpesvirus instead, and later on RSV is actually added to the list.

When House and his team list viruses that might be causing the infants' infection, they rule out the herpesvirus family but cite cytomegalovirus as a possibility. Cytomegalovirus is a member of the herpesvirus family (human herpesvirus 5); however, Cuddy's rationale is that the virus in question is resistant to acyclovir, which is used specifically to treat the herpes simplex viruses (and, hence, House writes "HSV" under the "No" column). CMV is not treatable with acyclovir and so it is still a valid possibility.

Clearly obvious fake infant in the beginning.

After the first infant dies, House and his team are discussing the reasons, there is a bottle of Nestle brands "Poland Spring" bottled water on the table. While Poland Spring is a Nestle brand sold in New Jersey, it is mainly sold in northern New Jersey as it's bottled in Maine. In reality, Nestle brand spring waters sold in western and southern New Jersey are Deer Park labeled which is primarily bottled at Frontier Springs in Pennsylvania.

When listing possible causes for the infection early on, the team quickly rules out viruses and parasites, leading them to conclude that the infection is due to bacteria. They never considered fungi.

House at one point says "the babies fell sick." As an American, House should have said, "the babies got sick." Hugh Laurie must have fallen into the British English version from habit.
