Here is an email I sent:
Dear friends and family,
Lilli is now six months! We can't believe the time has gone by so quickly, but there it is. Time goes and before we know it she'll be sixteen!! Eek! But before we get ahead of ourselves, we wanted to let you know how Lilli is doing.

She had her checkup on Monday and is now. . . 21 pounds, 28 1/4" tall, and has a 17" circumference head. She is quite a bit of baby to lug around. It's amazing how much babies change between four and six months. Since my last update to you all, she has started to say "mama" and "dada" (though not with much purpose, admittedly), sits up all by herself, eats cereal and sweet potatoes, plays with all her toys and tries to put them all in her mouth, including her own toes, and has two teeth! Two months ago I don't think she was even reaching for her toys.
