My two year old chocked on water a few times today while drinking from a cup. he keeps on coughing in his sleep every hour or so. should i be worried?

Pediatric exam: I suggest an examination. Your child may have inadvertently "inhaled" ( aspirated) water while drinking and should be examined and probably x-rayed.

Mgt.: Bronchospasm or an infection are among possible conditions. I agree that he should be evaluated.

See your doctor imm : Is there a family history of allergies, bronchitis or asthma? Your child needs to see the Pediatrician. He probably has inhaled a foreign body or he may be wheezing with asthma
