Hello! My baby is 7 weeks today, been having a few issues with her feeding.. We give her 3 oz every 2 hours, the last few.days shes have 1 ounce and fall asleep refuses more, sometimes ill wait it out 30 to 45 min and shell have one more ounce, im ok with her having 2. Then other times she is a bottomless pit... we'll give her 3 and she'll keep acting hungry so we give her max 2 more and.sometimes shell ask for more, should i consult with her doctor?
