Help!

Hollie

My 6 week old slept for over 5 hours straight tonight.. woke up with a dry diaper and it’s still dry so about 5 1/2 hours and he still didn’t pee after he ate. That’s not normal for him. He’s eating okay, but I’m worried. Should I be as concerned as I am?? Also, I’ve not noticed any other changes except he’s been more gassy than normal.
