Centiles driving me crazy!

Yes, it's fine. It's within the range.

Thank you @Reena I'm concerned as I thought babies were meant to follow a curve, not keep dropping centiles

You expect it to but ultrasound is also very user dependent and not always accurate. If it kept dropping perhaps there would be concern or it fell out of the centile window. I would discuss with your midwife/the sonographer.

Hi, my baby’s femur was measuring way behind. Measuring 24 weeks when I was 33 weeks. It was literally because me and her dad aren’t tall and my legs are really short. Her centile her dropping too but was always in range. I think it’s only a worry if it’s below 5%?

Thanks @Laura that's reassuring. Has baby been born yet? Both me and my partner are tall - im 5'9 he's 6ft so we expected baby to have long legs!

Yeah she’s two months and is fine, albeit has little arms and legs like me. Hmm, I understand your worry, can you talk to the sonographer about it? Get them to try and explain what it could mean?

My son’s femur was measuring behind, but I explained dad has short legs and I’m not overly tall and they weren’t concerned! They said the average is just a basic average, and that it’s helpful to have info on you & partner to see what the ‘norm’ is for you. My baby is 8 months now and perfectly fine 🩵

This is fine. Both my babies femur lengths always measured 2-3 weeks behind. Me and my partner are both very short and I have short legs. It's still within range ☺️

My son’s femur measured behind for all of his scans. He’s now 3.5 and in age 5-6 clothes and the tallest in his class. Your baby will be fine. Following the curve is more after they’re born as the scan measurements have such a high margin for error
