Anyone notice more fussiness with Ranitidine? We started it Friday. She's 6 weeks which I know is usually the peak of fussiness and major growth spurts (per wonder weeks.) Naps have been a disaster during the day with 20 min incriminates and she would not let me put her down yesterday. Sleep was better last night but a struggle to get her happy and down at 8:30pm. She then slept until 2:30am feeding time and then again until 6:30am. Woke up fussy again though. This a 6 week stage or a reaction to the Ranitidine? I just want a happy baby. Reflux is miserable.
