It is scary to hear news of a big baby...

BUT! What happens is that your baby is measured and a weight is deduced from those measurements. So a long baby or one with long limbs, a larger head whatever will stretch that weitght out. U/s estimates of weight are notoriously inaccurate at this late stage of pregnancy.

Your results are fine. Your baby is growing. You don't need to change your dates. Let go of the fear of a big baby. More often than not those estimates are not accurate.

Sending you a big hug and lots of reassurance that all is fine...
