Three of my four children did not take a bottle. Vanderbilt has a great lactation dept and they told me that latching on to a bottle and latching on to a breast is different. Some children are never able to take a bottle.
My second son could not form his mouth correctly to latch onto a bottle. He switched feedings and nursed all night long and I started him on cereal and a cup of breast milk at day care at 3 months old.
My daughter would not take a bottle either. I ended up quitting my job and staying home to nurse her for a year.
With my last son my employer did not want me to quit my job and they let me bring the baby to work with me until he stopped nursing.
Talk to Vanderbilt's lactation dept and see what they suggest. I did different things with each baby. Figure out what works for you.
