I think the best way to become more comfortable breastfeeding in public is just to practice and start learning what works for you and your child. Whether you practice in a comfortable setting like a La Leche meeting where there are lots of breastfeeding mothers and you can see what they are doing and you can kind of learn what works for them or whether you start off at a friend´s house using a cover to initially get the baby latched on while you are comfortable doing that and then moving on to different places, maybe a park where there is not so many people or more of a covered area and then just moving on from there. I think just practicing it and then learning that you can get your baby latched on and really people do not notice so much at all is the best way to get comfortable breastfeeding in public.
