I’ll bet it’s just to rule things out. When Evie was about 10 weeks, I had to bring her in for a cranial ultrasound to see if there was some other reason that she was crying. Of course, it came back fine. Can I make a suggestion on naps? Only b/c I have the same issue w/ the cat naps which I think are a contributer to Madden’s crabbiness. I put a heating pad on HIGH on the bed. Once I rock him to sleep, I remove the heating pad and put him on it, on his belly. I know, belly=so bad, but it really helps him sleep. Then I will put a blanket on top of him, the heating pad on low on top of that, then I just wait 5 minutes and remove it. This has been working really well for a 3 hr. midday nap. Forgive me if you’ve “tried everything” just wanted to share that I thought we had tried it all too and this ended up working. . (for now!)
