Help! 1 year won't drink reg milk.

AC • ?
Yesterday, my doctor switched my daughter to regular milk. Previously, I've tried vitamin D (before she turned one), She pushed her bottle away. Yesterday, I bought Lacaid whole Milk. She won't drink it. She was on Similac Alimentum. She knows the difference in her milk. Without it she screams. Any idea or has any parent gone through this transmission with their child from Alimentum to regular milk?? I'll try anything!!! Thank you!
