Possible IGUR baby

When I was pregnant with my son I had ultrasounds every week to check on him and myself due to having two pervious pre term labors. Anyway during that time my doctor got very concerned with my baby because he was not growing as much as he should have I was givin 4 rounds of steroid shots for his lungs just in case of an early delivery due to all of this. Well anyway they sent me to another hospital for a better picture of him and they said he was at a normal range and it was all okay. Well I came back home had my normal every week ultrasounds and every single time he kept measuring small and not growing as much. I just over looked it being I was super confused from the other hospital. Well I delivered him at 38 weeks 5 days pregnant. And even then he was only weighing 5lbs 11oz. They staff were surprised how small he was at that far of a gestation. Preemie clothes were even big on him! Fast forward; he’s now 9 months old and had his well child check today and the doctor said his weight is still only in the 17th percentile now. And that he’s not crawling or trying to pull himself up on things to stand as most kids his age would be. He doctor then informed me that In July when he turns 1 that if there is no change in him that he will have to due further tests as to why all of this is going on. I did not think about all this again until today! My baby has been 17lbs for 3 months going on 4 now with no gain, no change.

Mind you he will be 1 year old in 3 months and still only weighing 17lbs.!

Does anyone else have a baby that has IGUR?
