From my weekly newsletter:

Q: Why am I so forgetful?

A: The most probable explanation for your "mommy brain" is a simple one: You're tired and distracted. "As the mother of a 6-month-old, you're likely to be sleep-deprived and focused more on your baby's well-being than anything else," says pediatrician Jennifer Shu of the Children's Hospital at Dartmouth. "It's natural that you're letting less important things fall by the wayside." There's also a chance that your hormones might be making your memory a bit fuzzy, particularly if you're breastfeeding.

This does explain a lot, example, I asked Laura three times within 20 minutes if she had plans for tonight.
