My baby's have BIG Heads

My babies heads were 48cm (Seth), 46.8cm (Emilia), and 48.1cm (Aiden). Emilia was 75 percentile for head size and length. Emilia is 30 inches long, Aiden and Seth were both 29 3/4 inches. Seth is our butterball at 22lbs, Aiden at 20lbs 11 oz. and Mia was 18lbs and 15 oz. She gained good weight these past few months! Not bad for triplets born 5 weeks early!
