When my daughter was around your daughter's age, I gave her s-26 step 1.
I think that is normal if you introduce the milk to her, same like us when drinking milk after so long not drink, feel like our stomach is restless. But, need to be careful if there are any possibility of lactose intolerance (this one I do not know much). This one you need to monitor. Try give her few times the anmum, anything wrong, see paed.

I have bought karihome once for my daughter. Bought because she had prolonged jaundice. And heard goat milk can help jaundice go away. But stopped and changed to s-26, a lot of people say goat milk is quite 'hot'.

Now I use anmum for my daughter, step 3. I prefer anmum because it has lowest added sugar compare to few brands of milk. I have used s-26 step 3 for 1 or 2 boxes, when I shake the bottle, it forms a lot of bubbles, mixability for me is quite bad. Try taste the milk, got a funny taste. But for anmum, mixability is excellent, no bubbles at all. The taste is like a normal milk, no funny taste. Not promoting anmum though.
