Chrissy Teigen nails toddler years in single tweet

Celebrity mum Chrissy Teigen has nailed motherhood in a single tweet, again.

This time, her comment addresses the myth of the "terrible two" which, much like the phrase "morning sickness", is completely misleading.

Teigen, like mothers around the world, feels the "terrible threes" are much, much worse.

"I have discovered a mother's favorite thing to say: "it's not terrible twos it's terrible THREES ahahahah," she wrote.

Mums around the world then contributed to a stream of Tweets which pretty much covered the difficulties of parenthood from birth until, well, forever.

Dana wrote, "Terrible twos, frightening threes and the f**king fours."

"Or as I like to call it "threeyonce". Or "threenager," said Gretchen.

Joshua Tweeted, "For sure my favorite part of having young kids was all the parents who told me repeatedly “Just wait! It gets worse."

And CR said, "My FIL told me 'terrible twos start when they're 18 months and end when they're 25'."

The response to her wise words were instantaneous, leading to an additional Tweet which triggered another parenting stream of consciousness.

"It's not terrible twos it's terrible threes hahah it's notterribletwositsterrible threeshahahaitsnotterribletwositsterriblethreeshahaitsnott."

Yup. the model mum nails it again, and then again.
