Hey guys. Im new to the forums. this is my desperate plea for help. I had my baby girl on May 15th. She weighed 6.10 at birth. We went in the monday after and she was 6 lbs. I know that babies lose weight after birth but that they should be back at their birth weight by 2 weeks. We went in because of Thrush at exactly 2 weeks. She was 6.5. They didnt like that she wasnt back at 6.10 but they said to keep EBF like i am. Well we went in for a weight check yesterday (a week later) and she is down to 5.10. I let the dr know that she is trowing up about 2-3 times a day. It wasnt projectile vomiting but it was def a lot. The dr sent us to go get an u/s done to check for pyloric stinosis. She passed that with flying colors. I believe that the throwing up has to do with the weight loss. He said he doesnt believe it do because its not after every feeding. She is classified now as "failure to thrive" because of her weight loss. the title alone scares me. Her diapers are great. We get plenty of peepee and poopie dipes a day. We have checked for tongue tie and she is clear of that as well. We were having some latching issues that have been fixed within the last week. Any thoughts? Im so scared and thinking of pumping and switching to formula just until she gets her weight back. right now I am pumping and giving her BM so that we can keep a record of how much she is taking in. We go in on Monday for another weight check.
