Y’all I am concerned about my baby’s head circumference. Why is it all over the place every appointment. (Picture reference below) The last one says 10th percentile but she measured wrong, it’s not 16.0 inches I went home and measured and it’s 16.25 but even still that’s only 19th percentile….is my baby okay, is anyone else’s measurements all over the place?? Anyone’s baby’s head measuring small? It worries me so much. Pic of baby below for reference. I feel like she looks normal but I don’t know what a baby is supposed to look like.

She does have a flat spot on back of head,

Do that affect head circumference measurement s??!
