Can you suggest the solution to this puzzle?

50 newborn boys were born in a hospital and were kept in the same room. Due to a record-keeping error, the hospital does not know which baby belongs to which parents. There is no access to modern technology such as physical examination, DNA testing, footprints, or handprints. The parents cannot identify their children based on their cries, sounds, or other unique behaviors, and there were no witnesses present during the birth.

Furthermore, all the babies look exactly the same, with no distinguishable features or habits, and all the parents are identical twins.

The hospital needs to reunite the parents with their children, but there is no surefire way to do so as all the babies and parents are indistinguishable.

Can you help the hospital reunite the right parents with their children?

First you ask Reddit, then ChatGPT, then HN. Then you bikeshed the answers until someone points out some language quirk that passed unnoticed and reveals the answer.

Perhaps the babies were not born at the same time? Perhaps they put those little bracelets on the babies? Perhaps the babies never left their parents' side?

This is the North American way, I guess? So the question should be modified to include what country this happens in. Where I live, children never leave their parents' side. They pop out, get weighed in the same room, etc., and the mothers have a private recovery room for up to 5 days where both are monitored and taught some basics.
