Taking a breastfeeding class.
I can't stress this enough TAKE A LACTATION CLASS before birthing your baby. It makes such a big difference. We spend 1-2 days giving birth but we spend months to years breastfeeding. I will be offering a special group discount for my breastfeeding class, but I also teach one on one classes as well. I'm also going to be launching a members app for everyone to get exclusive content from me directly for just a small fee.
