My son is 8 months old and has been spitting up much more frequently and has been having super smelly poops, worse than normal! He threw up last night in his crib but slept through the entire night (for the first time) so since he didn't cry I didn't know he threw up. He has his two top teeth and the two bottom teeth. Could he be still teething from the teeth on the sides and this be the problem? He doesn't feel warm or anything but I gave him some Tylenol earlier and have also been trying to give him some watered down pedialyte.
