My newborn is 2 weeks old and for the past week or so has had very disturbed sleep from about 2-3am onwards. Initially, I thought it was wind but now I'm noticing it might actually be a reflux issue. He often spits up after a feed and when I put him down or burp him he will get the hiccups. Once he's laid flat in his crib he will grunt and move on to his side where he seems to be more comfortable but after that he will keep coughing and grunting and just seem uncomfortable. He doesn't cry but there's has been times where he's been that is uncomfortable is gotten to that.
He is mainly on Aptamil (First Infant) and has at least 1 bottle off my expressed milk a day.
I don't know what to do, any help would be great!
