Kristi - while Gabby hasn't been losing weight thus being tagged FTT, I have recently had a bad experience with my MCHN saying she is not getting enough to eat and that my supply must be low. I can completely understand where you might be feeling frustrated and how the stress of feeling like you are depriving your little girl is just unbearable.
Good on you for not continuing to go to the clinic. I am seriously thinking about doing that myself.
Gabby was born at term a healthy 8lbs and has consistently put on weight until recently where she has only been putting on half the amount she should. In saying that, she is happy, has plenty of wet nappies and sleeps sooooo well. I thought I was doing brilliantly until the MCHN said I need to do something about my supply (which I FINALLY thought I had down pat).
Gabby has yet to hit the 6kg mark and she is almost 5 months (and she wasn't prem). I am thinking she may just be a petite little girl?
I think your little one sounds like she is doing just right for her. If she is happy and sleeping well and doing all the things that a happy baby should, I say nuts to those stupid "averages".
