breastfeeding to cows milk

Sa

Okay so I'm still breast feeding my daughter and I send milk to daycare but she'll drink maybe an ounce there a day. she'll drink little sips of water from a sippy too. my milks starting to run out. I bf 3x a day but when I pump I'm getting 2 maybe 3 ounces. She loves yogurt cheese and ice cream and processes those fine. I'm thinking about starting vows milk sooner than 12 months but giving her vitamins. anyone else start cows milk early? I don't wanna use formula.
