mine was NOT able to handle anymore than 4oz of milk at a time so we tried soy milk and same thing. now she’s 15 months and still drinks half and half but it’s 4oz water 4oz milk and she’s been fine / off formula for a little over a month. so you can either wait till she’s older and try again or just keep her at a dose you know her tummy can handle
Give her full fat milk, under 2 years old they should be given full fat milk. It also just tastes better, thicker and creamier, so she may like it more.
Came to say the same as @Hessa - they should be having whole milk not 1% and it tastes better so they might like it more anyway. But also some just don’t take to it and that’s ok - make sure they’re getting other dairy in their diet for the calcium such as yogurt, cheese, etc. Also give a multivitamin daily.
If she doesn’t like it I’d stop offering it
