Old folks say that when the baby smiles, the new mother's hair will fall out.
In my case, Megan smiles first before my hair started to fall out. Megan is now not only smiling, she is laughing too. I hear her laugh in her sleep as well as when we tickle her. She is unusually an easy baby who is always ready with a smile - unless it is her sleep time.
And I noticed my hair falling out when the hole in the bathroom floor has clumps of it. Not as much as Ryan's time, but still noticeable. Apparently this has to do with the hormones trying to find its balance after a surge of it during the pregnancy. Once it stabilises, then it will return back to its grow and drop cycles.
