yup. parents' resopnsibility. I do provide homo milk, however. I also discourage bottles in general. Most of mine start at 11 months. I feel it's unnecessary. They should be drinking out of sippies. If they're thirsty enough, they'll drink. If baby still needs bottles at home, that's their business. I'm not a fan of toddlers and bottles. They're no longer drinking it to meet their dietary needs.
