The general rule is... if the kid can ask for it... it’s time to stop breastfeeding.
I have no problem what so ever with breastfeeding... I have no problem even with breastfeeding in public (although I would encourage women to use a cloth of small towel to cover themselves while they feed their child.
BUT
I have a HUGE problem with what THIS WOMAN did! This is out and out child abuse! and someone (either this woman or the editors of TIME) needs to be put in jail for this! I find it OUTRAGOUS, and is sexual exploitation of a child, distribution of child pornography and is no different than if TIME had a picture of that poor kid sucking on his dad’s wee wee.
CPS should get involved on this.
