In general there shouldn’t be a hormonal inbalance because the feeding of a baby is a normal process happening since the existing of human kind. So as long as you don’t feel unconfortable or you want to really make sure that everything is OK, you can simply continue what you’re doing. Just eat healthy and don’t stress yourself too much (if that’s possible with a hungry baby 😉 If you want to be absolutely sure or you feel unconfortable, consult your doctor to make specific tests to check if your hormones – and everything else – is OK or if there are things you can do to improve.
Breastfeeding welcomes more hormonal changes. Keep in mind if you are breastfeeding, cycles may be irregular or nonexistent for a year or more, meaning, without ovulation, you aren’t producing progesterone, the calming counterpart to estrogen.
