Has anyone used one?
My lo is horribly sicky and I saw it advertised and am wondering if it might help

I've not seen one before. It's interesting as some babies do get uncomfortable from the wind caused by bubbles, especially if you're using a perfect prep.

Are they uncomfortable when they're being sick or are they fairly relaxed, a happy puker?
