L weighs 13 lbs, 2 oz -- which is a little more than 1/2 lb more than she was at 4.5 months. She's still in the 10th percentile. She grew a .25 inch, to put her at 25 inches.
The pediatrician suggested I start giving her 2-3 meals of solids a day in addition to breastfeeding on demand. She's doing fine -- developmentally she's on target and she looks healthy -- she's just petite.
Her 2nd bottom tooth broke through last night. It explains why she's been unusually cranky the last few days.
