ONE MONTH OLD....I can't believe it

Zoe is 1 month old, today. We had her one month check up yesterday....here are her stats :

7lbs 4oz -- 5%
21" long -- 50%
14.25" head circ -- 20%

So, needless to say : she's long and skinny, just like her big bro! And, of course, the Pediatrician is "worried" about her weight. Good Grief, do we HAVE to start obsessing over our daughters' weight before they are old enough to talk?? He said they want to see 1 oz gained per day, and she'd only gained 4 oz in 6 days. My lactation consultant said the books say .5-.6 oz/day....so I never know what to think. The DR wants us to offer her a bottle of formula after every other feed, but what he fails to realize is that she is FULL after she eats! I can't force feed her formula! GRRR it's really frustrating.

When Daniel was newborn, and was >95% on his height and 95% on his weight.....I was told "we don't pay that much attention to percentiles and charts." But NOW that Zoe has such a huge discrepancy in her percentiles (5% for weight but 50% for height), they're worried. It is such a double standard. As long as she continues to poop, pee, and eat....then I'm happy. Yes, I wish she'd put on a little fat so her clothes fit before she grows out of them length-wise, but all this means is she'll be able to wear her clothes longer ;) Unlike Daniel, who outgrew his clothes in mere weeks!
