People were very quick to call Blac Chyna out on this photo of daughter Dream

"1 months old".

Dream Kardashian is now one month on this earth and to celebrate, she had a little impromptu Instagram photoshoot. The baby's Instagram account is curated by her parents Blac Chyna and Rob Kardashian, who posted the below photo to mark the four-week milestone for their first child. However, Instagram users were quick to point out the minor mistake made in writing "one months" instead of "one month". Oops. One person wrote: "1 months" is wrong spelling y’all". Another said: "One month*".

1 month ?

Although one month is indeed the correct terminology in this case, one person made the case that the other milestones will require month to be spelled plurally so there was no point purchasing a separate sign:

"Why people trippin about the 1 month thing,the rest of the months will have an s so people dont make another side that says "month".

Which camp are you in?
