My 2 friends and I had babies within 3 weeks of each other after 25 years of friendship. Our group chat became a lifeline.

Motherhood, she said, has brought them closer.

Our friendship formed over questionable decisions, break-ups, hangovers, and, eventually, the messy business of becoming adults.

Then, three baby girls born in three cities over three weeks started a completely new chapter.

Our connection became our parenting lifeline, proving that the best friendships grow with you.

"What a night!" "I barely slept." "I don't even know what time I went to bed." The same statements can have very different meanings in different stages of life .

My friends and I used to worry about where everyone was at 2 a.m.

Now, we worry about whether everyone's baby has pooped that day.

Laura-Kate (Lauks), Kirsten (Kirst), and I met 25 years ago at an all-girls boarding school in South Africa, then partied our way through university and early adulthood.

For years, our biggest problems were nursing sore heads with painkillers and junk food, who was dating whom, where we were going that weekend, and whether anyone had taken a particularly unflattering photo.

Then, the three of us had babies all within three weeks of one another, reaffirming our bond and allowing us to evolve together in new and exciting ways I never imagined.
