Re: mastitis or thrush???
Soy milk for a 9 month old? Your doc is wrong, wrong, wrong! Under a year, if you substitute anything for breastmilk, it should be formula. Soy milk does NOT have the right nutritional make-up to support healthy growth.
Many antibiotics are compatible with breastfeeding, and many doctors are misinformed about safety of antibiotics during breastfeeding,mand therefore recommend pumping and dumping for all but the basic antibiotics. For information on the safety of specific antibiotics, I suggest contacting the Infant Risk center: http://www.infantrisk.com/
Are you the mom who is in Buenos Aires? If so, and you're not into making an international call, let us know what sort of antibiotic you have been prescribed and I am willing to bet that someone in the US will be willing to make a call for you. That being said, I don't think it sounds like you need an antibiotic. You don't feel sick, you don't have a fever. And you do have burning pain, and the baby has white blisters in his mouth. That all sounds like thrush to me!
Additional symptoms of thrush:
- Nipples appear more red, pink, or shiny than usual
- Cracking, flaking, or peeling skin in the nipple or areola
- Small slit-like cracks which may be on the nipple or may radiate onto the areola
- Vaginal yeast infection in mom, or yeast diaper rash in the baby
Thrush is not a problem a lot of docs are familiar with. The exception is pediatricians, who are more likely to see oral thrush in a baby. I would take the baby to his doctor and see what that person says. If the pediatrician thinks it's thrush, make sure that a course of treatment (usually an antifungal medication like Diflucan or Nystatin) is prescribed for both baby and for you. You must treat both mom and baby, or one will reinfect the other as soon as treatment is over!
