Hi
I am in the same situation as you! My LO is sick so much, not projectile, and I have the frustrating situation of forever changing his clothes!
My LO is putting weight on and is otherwise happy and healthy! I tried the gaviscon but it literally did nothing!
I don't think my LO has reflux, I honestly just think he's a sicky baby and I'm hoping he will grow out of it.
As long as my LO is happy and content then I've just learnt to accept that he will get through a ton of bibs and clothes each day! I managed to get some weaning bibs that are basically bigger and go over the shoulders slightly so these are useful.
I gave up dairy as I was convinced that LO was intolerant but it turns out he isn't as I'm now having dairy again and he's exactly the same!
Is your LO happy when he is sick or does he get upset? Mine is never upset by it and often grins at the same time bless him!
