baby measuring under 10th centile

Sophie

My daughter has been measuring under the 10th centile from 20week we’ve been having growth scan every 2 weeks and been told to keep an eye on movements. Also be told could be having a my section at 37/38 week. I’m now 30 week and it’s got me thinking how much she’ll weight when she born and if to get some premature clothes and size 0 nappies. Guess my question is what was your baby weight at birth if they also measured under the 10th centile ?

They don’t having any other concern it’s just she smaller then they want.

Appreciate any experience or advice 😊
