Silent reflux. Gaviscon and comfort milk?

Jade

Our baby has been put on gaviscon for silent reflux, but apparently it thickens milk. She’s already on comfort milk (colic and constipation) for colic. Shall I keep her on comfort milk or move her back to normal milk? But I’m worried in case she ends up worse than she is now with being unsettled in case the colic comes back. She’s now on dr browns bottles too. What shall I do? X
