I am wondering if I should drop a pump session at work. My DD is almost 15 months and while we are off bottles at daycare she still nurses 3 times a day on average if I am home. I don't need the milk since I can send cows milk to daycare. I'm wondering if the resulting drop in my supply will help us toward weaning? My goal is to wean around 18 months but I'm not going to force her. Should I drop to one pump session at work?
