My DD had her 9 month check up yesterday and the pedi said her head growth jumped on the charts alittle. In November she was in the 72nd percentile and now she's in the 91st percentile. She said she'd like to see her back in 4-6 weeks and of course now I'm a nervous wreck! I personally think she's finally 'catching up'. She was 3lbs 4 oz when she was born 7 weeks early and yesterday she was 17lbs and over 27 inches long. Has anyone experienced a rapid growth? It confuses me because they want them to be 'average' but when they grow faster than what they think is normal, now theres a problem??
