Just do a search using "growth chart" or something similar....I could probably post a link but it's late..... ....sorry. DD was about that size at that age....she is about 20 pds now and is 7 1/2 mo. They come in all shapes and sizes, don't they?
And please note the paragraph that says: Are these charts appropriate for exclusively breast-fed babies?
The 2000 CDC growth charts can be used to assess the growth of exclusively breast-fed infants, however when interpreting the growth pattern one must take into account that mode of infant feeding can influence infant growth. In general, exclusively breast-fed infants tend to gain weight more rapidly in the first 2 to 3 months. From 6 to 12 months breast-fed infants tend to weigh less than formula-fed infants.
My breastfed (for 20 months) dd gained weight quickly in the beginning but now only weighs 25lbs at 2.5 yo.
My BF baby also gained so much in the beginning. Once he started crawling he slowed quite a bit. He was actually gaining two pounds a week! I was worried but his ped said it was normal. Then when he went from 6-9 months he only gained a pound. Again I was worried. Doc said It's normal.
