You wouldn't normally deliberately edit a couple so one of them comes across as controlling and dominant in an ad that is meant to be uplifting.
So the whole thing just gives the uncomfortable impression that either
A) the MTT is happy to be the one who talks, the one who defines motherhood, without reference to the experiences of their partner who carried and birthed the child, which is quite self-absorbed and domineering
OR,
B) Dove were only interested in the opinions of the MTT to the point of not requesting any contribution from the birth mother, which implies that Dove as a brand is consciously happy to erase 'boring' motherhood in favour of their self defined 'real' motherhood.
Both leave a nasty taste in the mouth tbh.
If both of them had talked about the experience it would have come across totally differently.
