Re: Should I be concerned about my milk supply?
It sounds like you, your baby, and your milk supply are all doing just fine.
Many breastfed babies slow down their bowel movements to every few days after a certain point. Their digestive systems mature enough to digest breastmilk very thoroughly, with little waste left over. So long as your baby is a) gaining weight, b) having a bowel movement once a week, c) having plenty of wet diapers, and d) feeding on demand, everything is in the normal realm.
Some (But not all) women notice a dip in supply when they get their periods back. But if you nurse on demand, your supply will bounce back to normal very quickly. It's not like your period returns and then your milk supply slowly and irreversibly dwindles away- that's an old wives' tale, rather like "Milk goes sour in the breast during your monthlies."
And the main reason I am worried that I may not be producing enough milk is that I got my period back a few weeks ago and wonder if the hormones are affecting my supply.
This sounds totally normal to me. In the early weeks/months of nursing, many women overproduce milk, which would explain why you could pump 2-3 oz of milk from just one breast. After a certain point in time (Different for every woman), your milk supply adjusts to meet your baby's needs very precisely, without a lot of extra left over. So long as you nurse on demand (Noticing a theme here? ), there is no need to worry about your milk supply. You can just let your baby regulate it- if he needs more, he'll nurse more often and drain you more thoroughly, and that will increase the amount you're making. If he needs less milk, he'll nurse less frequently and leave more behind, and your milk supply will decrease to meet his need.
When he was about 2 months old I could pump and get like 2-3 oz from just ONE side. Nowadays I don't pump regularly, but the few times I have pumped i only got like 1 1/2 oz from BOTH sides. That worries me.
