4 month regression – with Reflux

So little one is 4.5 months old and was doing so much better on the Nexium. We were up to sleeping for 7 to 9 hours at a time , taking reasonable naps (instead of 15 minute ones), and reflux symptoms were almost gone. In the last 10 days, we gone back to short naps, more nighttime wakenings, and reflux symptoms are coming back.

She’s back to screaming while she eats at least 2 of the times a day, arching her back while she eats and being just more fussy. She’s not having the 1 1/2 hour after eating meltdowns yet. And she’s started doing a single cough periodically while she sleeps. I think that’s reflux.

Most concerning though is that the last 48 hours it’s getting harder every time to get her medicine in her. I was mixing it, putting it in an empty bottle with a 6 month nipple I’d enlarged and as long as she was starting to get hungry, she’d gobble it up. It’s gotten harder each dose to get it in her, and now this evenig she refused it. Any that gets in her mouth she spits out. If you use a syringe to put it in her mouth, she spits it out (at least 95% of it). If it comes out of the bottle in her mouth, she spits it out.

I’m at my wits end. What is going on? Why is she all of a sudden refusing to take it?

I’m calling the GI doc tomorrow but does anyone have any thoughts? I’m thinking the sleep may just be the normal 4 month regression that a lot of babies go through, but since we’re having reflux symptoms again, I have to consider that reflux may be playing a role especially because of the single choke cough she does.
