So, apparently on the Motrin Website (which is currently down), there was this ad placed.
Most of the uproar seems to be at the condescending tone and content of the ad, mainly the idea that:
1. Moms wear babies in slings as a fashion statement, or to be trendy
2. Wearing babies in slings is a new thing
3. Moms are crazy
This is pretty fucked up advertising.
