We'd be so confused as well!
After more than three years of struggling to conceive, Heather was able to tell her family that she was expecting.
The vlogger told each person differently: via FaceTime, with the help of a plastic frog from her childhood and a number of individually decorated mugs.
And while each person's reaction is both sweet and brilliant, it is Heather's niece who wins the prize for best reaction ever.
As can be seen in a video uploaded to YouTube, the teenager, who is with her mum at the time, is the fifth person to find out the wonderful news.
Opening her gift, Heather's sister instantly catches on to what the mug (which has 'Auntie' written on it) implies.
However, her daughter takes a bit longer to understand what exactly is going on.
Clearly confused by the mug which says ‘World’s Best Cousin’, the teen needs a little prompting from her mum before it finally clicks - SHE is going to be a cousin!
We've seen plenty of pregnancy reveals over the years, but when you watch the entire reveal below you'll be taken on a rollercoaster of emotions, and a guaranteed few tears at the end.
