Son, you are now three quarters of a year old...that's 0.75 if metric catches on in the States by the time you are old enough to care.
For the stat keepers - you still have only 2 teeth, although I feel more coming under your pink and healthy baby gums. Your average hours of sleep per night has dropped back into the ~ 3-4 hours area. You weigh just under 20 pounds. Oh, and there's something else...
And suddenly, everything changed!
We love you, son. This year is flying by, and it's both exhilarating and terrifying to see how having a kid transforms the formerly quotidian into an exhausted, happy mess of a family routine.
