Okay the history first..
S is 2 months old
at birth she weighed 7 lbs even
when we left the hospital she weighed 6 lb 12 oz
at her 2 week appt she weighed 6 lb 13 oz
at her 2 month appt she weighed 7 lbs 11 oz
At her 2 week appt the dr. seemed a little concerened, but S seemed to be content, eating well every 2-3 hours with a 4 hour stretch most nights.
We are now more concerned after having her 2 month check up she has not gained even a lb yet.
About 2 weeks ago she started to get really fussy, brushed it off as colic it would start around 5:00 and last until bed time at 9:00. A week later it seemed that S was always fussy. Was/is always crying unless she is eating or sleeping, but will only sleep well if she is being held. It is as though she is always starving
I work part time in the mornings and am able to pump enough for her while I am gone, and I BF when I am home. I can usually pump 4 oz in the am and will usually be able to get 2-3 more during the day when I am home, so when I am gone S is eating about 4-6 oz in 5 hours (although part of that is her long nap in the morning). I think she is getting pleanty to eat when I am home cause I hear her swallowing. She is however a very lazy eater and falls asleep very easily and every time she eats. Even with a bottle it will take her 20 min. to drink 4 oz. In the afternoon I feed her on one side while pumping the other, switch sides and pump the other while she finishes the "good stuff" on the one we started pumping with, then if she needs more I will give her the bottle that we pumped (1-2 oz) she rarely needs this, but occasionally. Most of the time though she will just fall asleep and stay asleep as long as someone is holding her or she is in the sling, but if we try to put her down she wakes right up and starts crying.
The Dr. mentioned the need to supplement as she is not even in the 5th % for weight. She is fine for height and head circumference though.
What am I doing wrong? What am I doing right? How can I get my little S to not be so fussy and to gain weight. Is this fussy stuff colic? What exactly is colic? Is it what I eat? I am a very average eater, I eat a variety of foods, veggies, meats, pastas, starches...basically anything but celery.
S is my 3rd and my other 2 kids were BF until I went back to work, I didn't try hard to pump with them and gave them formula by 3-4 months they were on formula except at night. With S I really REALLY want to avoid formula and its expense. Please help me!
