Weight Gain!!!!!

I took Gwyn in for her 2 week checkup last week and to my surprise she had lost 1 lb from her birth weight! I totally freaked out and wondered what I was doing wrong. The doc. told me to bring her back in a few days later. I was breastfeeding and decided that I better make sure I was getting enough milk in. I totally wasn't. I was devastated to find out I only produce an ounce...for both sides. So, I had a decision to make..either keep breastfeeding (which Gwyn is a really LAZY eater. It would take her about an hour to nurse.) pump, and then try and get her to drink a bottle...which would consume about 2-3 hrs. Or just switch her to formula. I chose the latter. I took her back in to get weighed and she lost another ounce. I thought we really had a problem then. My mind was reverting back to thoughts of feeding tube placement. While we were at the docs. she was hungry, but of course I didn't bring anything with me. I thought we were going to be in and out. The nurse brought me some formula and a bottle to feed her. To my surprise she ate almost 4 ounces! The nipple on that bottle was a life saver! I took little miss Gwyn in today to get her weight re-checked....She gained 1 lb!!!!!! I couldn't believe it! I feel so much better knowing that she's actually getting full! Poor little thing being starved! So her weight as of today is 7 lbs 1 oz! Almost back to her birth weight!
