Is this normal behaviour for a teething 6 month old? The last few days he has been sooo grumpy, not like his usually happy self. He ocassionally stiffens his body and screams and grunts and moans and doesn't want me to put him down. Periodically throught the day except when he is sleeping and eating (and sometimes playing for short periods). I took him for a walk and that seemed to calm him down. He is not gassy or constipated. Could this just be from teething or is this behaviour something I should be more concerned about? I'm a FTM and I heard teething was hell but I didn't think he would be grunting and groaning all day and for days. I expected more crying and cuddlier. Thanks!
