How accurate have people found scans to be at showing their babies weight? I had a 4D scan done today and she said baby is already 3lb 14 and I'm only 29 weeks. I'm petite at 5ft 2 and size 8 so I'm panicking about him getting really big. At my 28 week midwife appointment my bump measured 6 days behind 🤷🏼♀️ x
