Dear C.,
I do not have any experience with my babies throwing up breastmilk when they have a fever, but I would encourage you to breastfeed as often as you can. Your milk has antibodies that can help the baby fight off infecttion. It is amazing.
Make sure to watch for signs of dehydration if the baby continues to throw up.
As for the baby's fever, I have a few suggestions for treating the fever naturally. If you are interested, please let me know. I would be happy to help. I have four children (ages 8, 6, 3, 1) and we have given only one antibiotic in 3 1/2 years (when I learned about natural options).
