Babies. All one gender?

What's the highest number of babies you've had in succession that were the same gender (i.e. all boys, all girls)? For me it was only four. The third generation of an old family I used to play had all daughters for the longest time before an "unexpected" pregnancy later in their adult life ended up breaking the pattern and giving them a son. Now a new family I've been playing for a while are at three sons, so I'm debating trying for a fourth kid later on (and then possibly a fifth) to see if I can beat the record.

Have you guys beaten that record? No cheating allowed to impact the gender btw.
