I think Grant is a meth addict

It is now 5:11 p.m. Grant hasn't slept more than 20 minutes since 3 a.m. (and neither has Mommy). He cries and cries and cries, won't sleep and when I try to feed him, he attacks the nipple like a crazed addict, then moans in discomfort. He's not sick, just fussy. All the signs of a tweaker.
