I was totally struggling with BF when my DS was about 6 weeks old. He was gaining weight but VERY slowly. My stupid GP told me to totally abandon BF and feed formula. I asked if I could dual feed since I didn't know at that time I could get through it. He said "yes" I could but I should still feed my baby 120mls of formula at every feed. "what if he won't take it?" I asked because I had had this problem with feeding him EBM. "keep going 'till he finishes".
What a total tool.
If you are in Queanbeyan I am happy to PM you the name of this guy......good Dr but ****e at BF stuff.........
