No, not yet. We just got the Sucraid to help Mathieu be able to eat more foods (because of his CSID), so we're focusing on adding new foods for now and when we're a bit more settled, I'll make the switch.
The issue I have now is that goat's milk (like cow's milk) has less carbs than formula, and so until I can get M to eat more carbs (thanks to Sucraid!) I need to keep him on that for now because the lactose was his only source of carbs in his diet and he's not getting enough as it is already.
