formula to milk

sugarmag9178

My dd is almost 11 months and I've decided to slowly start the transition from formula milk. She had one ounce in her 6 ounce bottle saturday and was way fussy saturday night I can only assume it was the milk. Im trying another ounce today to see if she gets fussy again.

 Do I just continue in hopes that her body is just not used to the milk and it will take some time to adjust?

 Or do I stop the wcm all together and try something else like lactose free? soy? almond?

 any help would be appreciated!
