Ahhhhh help!! I'm excited. My little man nursed for the first time in months! I thought I'd feed him baby food, give him a bath and get him ready for bed and then try to nurse him while he's in his daze and automatically I felt the let-down reflex even though he didn't nurse for long. I am currently feeling the let down reflex right now but not leaking. Does this mean my supply is increasing? I've been trying for so long to increase my supply. I hope this is what it means.
