DS is about 4 1/2 months... I just feel like he doesn't eat enough, though he is definitely gaining the weight he needs. He's consistently been 85% for both weight and length... he's 15 1/2 lbs. But my letdown is SO SLOW and he doesn't nurse nearly as long as he used to... I can tell he doesn't get tons of milk per gulp from me... even when I occasionally feed him from a bottle I can tell he gets tons more from the newborn flow nipple than he does from BF from me... And when I do occasionally give him a bottle he only drinks 2-3 oz at a time even though he's close to 5 months old... and since he doesn't nurse as frequently as he used to it just worries me.
