Breastfeeding mums.

I asked this in the breastfeeding forum but have yet to get an answer.

I have no clue if this is new or I’ve been experiencing it all along. Embarrassing that I can’t recall.

But I just noticed my nipples are constantly hard. What gives? I’m thinking it’s an early pregnancy sign. I’ve been breastfeeding eight months now but can’t recall if it was always like this!

Any EBF mums have this regularly?
