I’m not sure if this helps but Alana loves this position when she is awake. She will often lean back over a toy or an arm or something. I think she likes the view from there
. Her reflux is controlled and she doesn’t seem in any pain… so in some it might just be a nice position to be in? In saying that, I know that the arching is common in reflux…i think it is them trying to stretch “that thing I can’t spell” out to get some relief. I’ll be interested to see if the pepcid makes any difference.
