My little girl spits up quite a bit and has bad gas. I use Similac pro sensitive right now. It doesn’t seem to bother her too bad but I have to change her clothes so much because of the spit up. I’ve tried gas drops and gripe water. Neither seem to help much. What have y’all used that works the best? ( I do understand that she might just be like this and that there’s possibly not much I can do. )
