Veronica,
to make you stress less (I use this for myself too) I offer boob every 2 hours or whenever Zy doesnt settle & tell myself it's a growth spurt! It takes away my mental thoughts of 'no supply'...
I knwo I have tommes of milk, but whenever they just dont settle you instantly blame yourself!!! So just offer boob more over the next days & if she needs to boost your supply that will do it & you'll take away the guilt from yourself!!!
