Hugh and Lucy are home sick, so while they veg upstairs, I'm relegated to the basement. This means I'm forced to watch TV as it happens....which includes commercials (rather than watching what I record on the DVR). So, I'm flipping between Mighty Ships and Bringing Home Baby.
It's a first time mom. Her best friend visits, she has a toddler. You hear her ask the new mom if she can hear the baby swallow, which is answered with a yes, and the friend replies that that means he's getting milk. The next day, the mom goes for the baby's check up, and comes home with instructions to supplement "a little, 20z" because her milk is slow in coming in.
WAIT!! Giving a bottle will mean your body isn't going to be told that it NEEDS to make milk! Your body is going to think "oh, I should slow down a little, there's no demand". Nursing MORE will increase your milk. You might say "oh, but baby is still hungry an hour after I nursed". Then nurse again! You might say "I nursed for 15 minutes and he's still fussy". Then burp, and change breasts and nurse some more! If, after that, baby still seems hungry, then offer supplementation, but by finger feeding or, even better, by a supplemental nursing system so baby is still nursing and the body gets the message it's got to step it up. Leaving baby with grandma and a bottle while you go to do laundry is NOT going to increase your milk supply. Why is it so hard for doctors to understand that? Oh yeah....a pediatrician is not an expert in normal infant feeding needs, or breastfeeding. Duh. That's like going to see the dentist because you have a stomach ache, and gee, the food starts off in your mouth.
See a lactation consultant for lactating troubles. They're the experts.
