my son might have swallowed something but im not sure. when i walked over to where he was playing because he was coughing his eyes were watering i picked him up and he seemed fine. i found a piece of a basket the dog had chewed on the floor and figured he had tried to swallow it and spit it out. hes now woken up a couple tmes since putting him to bed and the second time his tumy seemed hard but he went back to sleep very quickly after i went in there so i dont know if hes uncomfortable or not...shoud i be worried? shoud i just wait it out?
