That's what it looks like on one, like a blister, it looks a bit white on the end when she comes off. No, it's not symetrical, it looks like she's sucking more of the top of my nipple coz it's pulled out more than the bottom. The LC said the shape was ok but I don't think it is. I don't know what needs to change though like what part she needs to get more of to make it more symmetrical. Nope hasn't been checked for tongue tie.
OMG she needs to feed again now off the sore one, wish me luck.
