Baby 1 was born at 9lb10, HUGE and ended up on the 9th centile at the end of the first year (I had to look in the book as I remembered her being petite but hadn't twigged it was quite the dramatic!) However as she had whooping cough badly and then crawled very early before getting a chance to get chubby noone worried and I was happy she was happy etc.
However this one is only 8 weeks and already dropped 2 lines from the 2 week measurement. (It would be more if they did it from birth, 9lb 14, but they start at the 2 week mark). She is also very long (98th percentile) so she probably "ought" to weigh more to match her length.
I wasn't actually worried until my HV rang me after a weighing clinic, and then a home visit today. Should I be worried? What will they do? Are they going to suggest formula?! Baby one was ok....
