At 4 months, Eliza is 13 pounds, 11 ounces and 24 1/4 inches long. She is at the 36th and 37th%iles respectively for her age. So, while she looks like a chunky little girl, she remains below average! It boggles my mind! As far as developmentally, she is still exclusively breast fed, she can roll from stomach to back, lift her head up to just about a 90 degree angle, smiles, coos and laughs. She loves her swing and often naps in it. She has slept through the night once! From 9pm to 6am! Since then she has not repeated it but has gone on 4-6 hour stretches of sleep. She definitely prefers her Mama and is getting used to her brothers and sister always being around.
