There are important factors worth considering when looking for good breastfeeding activewear.
Comfort and Support
Support is critical to the upper body given that a nursing mum has engorged boobs. Working out while breastfeeding is not the time for light and flimsy tops. The breasts are heavy so they need medium support. The materials should be tough enough but gentle on the nipples.
A few Sizes Up
The cup size increases after pregnancy so it is good to size up when buying new sports bras. There should be room for nipples to breathe to avoid compressing the milk duct. An extra room for the lower body goes a long way to support the added weight. A bigger band size would come in handy to accommodate the rib cage and the waistline.
It is advisable to choose all-purpose bras as it can cater to different activities including feeding in public and working out. Generally, the body feels denser so it is good to go with activewear that feels comfortable to run in.
