Serena Williams needs help with baby teething

With one Instagram post, Serena Williams summed up parenthood for everyone, whether you're a 23-time Grand Slam singles champion or not.

Here's what she wrote on Sunday about poor baby Alexis:

As a parent myself, I completely sympathize: Teething is the devil, and in general, there are times when you're a parent when you want your own mom or dad to come over so he or she can comfort you like a child.

Serena: The only advice I can give is that this too shall pass eventually. And that's the worst, but it's true.
