Just wondered if anyone any thoughts on this. I have a 8mth old DS - my 2nd child and am 43. This time body not wanting to get back to anything approaching acceptable shape. Used to run a lot before children and have decided to take it up again as less time consuming than having to go to a gym - and more flexible. Am breastfeeding though and just wondered if it is OK to run. Will all the joggling about have any effect on milk supply/flow?? Obviously will wear armour-like sportsbra. Anyone know???
