Bless your heart -- and a new Mom too! Oh boy, you have your hands full. I'm so sorry you're suffering from this, but I hate to tell you that it sure sounds like brain fog from Fibromyalgia.
I think the brain fog is the worst part of Fibro. I have days where NOTHING makes sense. My head is full, but I don't know what it's full of. LOL I guess I have to laugh because what else can I do?

I end up such a confused pile of humanity, it's funny.
Gosh for you to get brain fog isn't funny at all -- and you MUST have your wits about you. I'm 64 yrs old, and a widow -- I don't have to do much of anything because I'm disabled. My son lives with me, and if anything needs doing, I'll make HIM do it.
Dearheart -- my prayers are with you. I know you can't be on meds right now due to breast feeding --- but should you decide to wean your baby so that you CAN get on some meds, perhaps you'll feel a little better. I do APPLAUD your decision to breast feed. It seems too many younger people just don't want to bother with that anymore. But babies ARE healthier when you do, so thank you for caring so much about your baby's health! You're a GREAT Mom!!

And the bonding you get is SO special.
God bless you and keep us posted as to how you're doing, will you? Big hugs, Lee
