My baby had her 1 month appointment today. She is in the 50th-60th percentile range for height and weight, but her head circumference is only in the 25th percentile. She is growing normally according to the growth curve, but the small head is slightly concerning for me. Her pediatrician didn't mention it, and he is thorough and I trust him, but wanted to hear others experience. Is head circumference related to intelligence? Will she end up with a disproportionately small head as an adult? Any insight would be helpful. TIA!!!
