baby pattern baldness

Somebody explain this to me…

Here’s Lucy’s hair when she was 3 weeks old.
Post-bath rage!
(It’s terrible that this picture makes me laugh, isn’t it? TINY FURY!!)

And this is what her hair looks like now, at almost 19 weeks.
Worst nap buddy ever. She won't stop "talking" and let me sleep!

WHERE DID HER HAIR GO?!?!!

I remember that something similar happened with Catie, so I went digging through the archives and found this.

Catie at 2-ish weeks old:
spiky hair

Same full head of dark hair that Lucy had when she was born, right? But by the time Catie was 4 months old:

Tummy time

Her blonde hair was well on its way.

So, I’m just baffled. What is with Lucy’s head? How can a baby go from a full head of hair to almost zero hair? Isn’t it supposed to go the other way?

Since we have to get out of the house for a showing, this one & I are going for a walk.

Luckily, she’s cute enough to pull off the look, but I have a feeling that when she’s older, she’s not going to like that one of her nicknames is Captain Baldy.
