The usual response of the computer, upon the creation of a profile, in the event that two children are born too close together in time is to issue a warning for the PM to verify the data.
The computer does not notice there are two different women involved. This is not a bug in the computer system. At the time of creation of the profile and thereafter, each time one of the two profiles are opened, and the warning is issued, you just press SAVE ANYWAY.
I have perhaps a half-dozen of these in the profiles I manage and have never yet seen them presented in the Suggestions where errors in data are listed in order to address them
And in several cases, the computer, by flashing that warning, enabled me to correct errors in the data I had made
