Here is a simple diagram of some of the positions of breastfeeding.
In reality it often depends on the size of your milk jugs, boobs, breasts what ever you feel comfortable calling them or how tired you are. It is much easier to use the football hold if you have larger breasts. If you are completely knackered which you are often in those early days, the lying down hold tis the best!!
The most sociable one is the cradle holds as you can be a little more conspicuous when in public.
I think this is the last of our breastfeeding series, but more to come on the bottle feeding.
