I was intrigued by all these ‘my baby was reciting the complete works of Shakespeare by 11 months posts’ (especially loving the one who could recognise and identify colours, cupcakes (which I’m sure an 12 month would never have eaten) and remember to be polite enough to say please). So I had a look on YouTube as I’m assuming all these parents of baby geniuses would have recorded something interested - so far no requests for pink cupcakes. If anyone finds a video I’d love to see one as I am highly skeptical (bearing in mind that the milestone is 50 words at 2 YEARS* )
I’m also chuckling at some of the posters asserting that they said 50+ words at that age. Assuming it’s not your super memories and that your parents have told you this, do you not think it may be possible that your parents have exaggerated (Lets be honest, we all do as it parents).
Your comments are incredibly snide and rude, and you are actually coming across as rather bitter.
So what if the average milestone for saying 50 words is 2 YEARS! ?
(I doubt that myself - but I am sure your youtube source is obviously correct!.) 
All children are different. So some will be saying many words BEFORE that.
The average age for a child to walk is 9 to 12 months, but my DD didn't walk til 17-18 months old. But I am not sitting here calling people liars, and scoffing at them, implying they are talking shit, if they say their baby started walking at 10 months old.
Be as sceptical and sarcastic as you like, with your silly 'people who say their baby is reciting Shakespeare' line (which no-one has!) but it doesn't change the fact that some babies can say 50+ words by the time they are 12 months old. Just coz YOURS can't/couldn't, there is no need to be bitter, and scoff at people whose babies CAN.
As i said, my DD didn't walk til she was 17-18 months old, but I don't sit here implying people who say their baby walked at 10 months old are full of shit.
As for the poster who said her friend was deluded because she said her baby/toddler could say several dozen words, but she (the poster in question) could only hear babbling. As another poster said, many mothers can understand what their baby is saying when other people cannot.
Like regional accents... When my 2 pals from Glasgow start a conversation, most people can't understand half of it because of the way they pronounce some words, and the slang, and the dialect. But I can, because I hear them speak - a lot.
