pyloric stenosis

Anyone out there had a baby with pyloric stenosis? Mine had surgery dec 13 and still think there might be something else wrong for the past 3-5 he had slept ALOT MORE than normal he is 1 month and 18 days idk if it's a growth spurt or what but he is eating and keeping it down happy when he is awake no fever VERY gasy only pooping once a day or every other day hates burping fights it squirms and uses legs to push off whatever is in his way and grunts a lot. Is this normal or am I making a mountain out of a mole hill and being one of "those" 1st time moms? I def have my guard up bc of him having surgery at only 28 days old and thoughts or suggestions would be appreciated
