The character Lisa on
Six Feet Under breastfed her daughter, Maia, past infancy. I'm pretty sure Maia was over a year when Lia died, and she had just pumped herself silly so as to go on an overnight visit at her sister's without the baby. Lisa said she would "pump and dump" when she was out and wanted to drink more than she thought advisable while breastfeeding and there were a number of other references to breastfeeding that were the most realistic I've seen in pop culture. That said, I don't consume a lot of media and
Lisa was portrayed as the crunchy type, so it wasn't as if the writers and producers of the show were necessarily positioning breastfeeding as normative.
