It is possible, but it is best to talk with your healthcare providers (primary care doctor, rheumatologist, obstetrician -- all three) before beginning to breastfeed. The reason, as you probably know, is because some medicines can pass through your breast milk to your infant. Someone on your healthcare team will know if your treatment plan is complementary to breastfeeding.
Consider, too, that breastfeeding can be tiring -- even exhausting -- because breastfed babies eat more often than those fed with formula. By using formula as a supplement, or pumping breast milk so that your partner can feed the baby, you may be able to reduce the work of breastfeeding.
