I've noticed a lot lately that Linus's joints crack a little when I pick him up. I'm being careful with him, but when I pull him into my chest, I hear these little cracking noises. Any ideas? He's also been having some breathing problems lately (sounds like reverse sneezing into a microphone...or an 80 year old smoker). He does it about 4-5 times a day and it's getting louder and more frequent. Help, my baby is breaking!
