My little guy was 5lb 5oz when he was born. I had high blood pressure so that was the reason for my peanut.
My baby grew so small they thought she was going to have issues! She was about three weeks behind by week 35. I had her at 39+2 and she was perfectly healthy at 6lb 5oz and 19 inches. Sonograms aren't always accurate.
With my first daughter she measured 1 week behind and my doctor said that she was going to be a small petite baby. And she was, 7lb 11oz 20.5in and long and skinny.. and she is healthy. She was born at 37w2d.
How many weeks are you sweetie?
