Hi my lmp 20.01.2018. I delivered baby boy on oct 22 2018. During pregnancy I have done nt scan. Steffan scan and growth scan.in all those scans edd was changed.in first scan ut was nov 8 and in steffan scan it was nov 15 and in last it is nov 22. Doctor told me it's iugr. I asked if I born with a baby 4 weeks lag growth behind any abornamalities. She said not sure. At birth his weight was 2.2 kg and height 84 cm and head circumference 32 cm. It was normal delivery. Abdominal was very thin. He was not kept in nicu. I was feed him to 7 months. Then formula and solid foods introduced. He was now 22 months old. He is not responding when I call his name. He is not speak a single word till now. His motor and sensory skills are good. Speech delay. Even if ask him anything to bring mobile or anything else he won't understand. Because of this iugr growth lag. His brain development growth was not done. I'm really worried a lot. Same age child of his age are speaking, understanding. Please give me guidance.
