Is this normal?

I started slowly weaning Sage onto whole milk yesterday.  She seemed fine.  But she woke up at 3 am with a gurgly belly.  And this morning she spit up a little.  Is it normal for them to have that reaction?  I only subbed one ounce of formula for milk as per dr's orders.  TIA ladies

Not sure if it is normal since Max had no problem with milk. Is she on soy formula? Maybe hold off on it for a couple day then try again to see if she does the same thing.
Good luck!

Could be the whole milk is too intense for her little system. You could try 2% milk mixed with breast milk or a lactose free formula and if she still has gurgly issues you might want to try lactose free milk.
