Head circumference grew fast

Ro

I just had my 2 month appointment for my baby. They said her head grew fast as it went from 33 cm when she was born, 34 cm at 2 weeks to now 39 cm at 2 months. Which is 71 percentile. The ped wasn’t concerned because she said she’s overall grown a lot. She left the hospital at 5 lbs 10 oz, height at 19.25 and now weighs 10 lbs 10 oz height at 22.24. The ped thinks it’s just because of how much she’s grown. But now I’m so worried. I’m going to go back at 3 months to check. Has this happened to anyone and everything’s been okay?
