I think baby probably would be in NICU/SCBU for a short while, especially if baby is only small. They were very accurate with Ethan's weight, they estimated 5lb and he was 4lb 14oz so like 1-2oz off, which is pretty damn close. He was by far the biggest baby in NICU but also needed the most care due to his condition. I suppose it would depend on why baby is growth restricted and if there are any other underlying issues. On the up side Ethan was only 30 weeks gestation and although he needed ventilation he was on the lowest level of oxygen, he could pretty much breathe fine for himself, I had only had two steroid shots the 24 hours before he was delivered - at 36 weeks baby is fully developed and almost classed as term.
Good luck honey, I hope baby can stay cooking a little longer xxx
