Anonymous wrote:My five month old does this weird stiffening/grunting thing when he's upset and especially if he's tired. He'll clench up his fists a little, straighten his legs, and arch his back slightly, and make a straining/grunting sound. This happen especially when I'm getting him ready for bed (so he's tired) or when he's upset at being put down (when he's tired/fussy and wants to be held). He'll also do it occasionally when he's trying to do something and having trouble, like trying to get to a toy he can't reach. What in the world could this be?? He doesn't seem to have reflux and otherwise seems pretty normal - happy/social, rolls tummy to back, likes playing with and sucking his toes, etc. I don't think it looks like a seizure but it's kind of freaking me out. I will mention it at his 6 month checkup, but in the meantime, any ideas?
My DS does this too, I just took it as him expressing his frustration. NBD.
