I have no idea but there was speculation she was pregnant before marriage not sure how true it is though
There have been people saying Molly had the baby already, weeks ago, even now on other sites it is being said the baby is 2 months old and does not look like a newborn, the way a new born is dressed is different, not those big shoes and a full Gucci jacket, it all looked so uncomfortable to put on a baby in this weather too,
The main channel has not been posting vlog's on a regular timeline, a lot has been hidden and they have been showing old content, In some vlogs Molly would look bigger.
It is obvious she was sick on the honeymoon and they chose not to vlog after that.
