<s>[INST] hello, my baby is 9months old and every few hours he tenses his face, neckandshouldersand looks like hes pressing or pushing. H edoes it for a few seconds and stops. He has just come off anti biotics a week ago for middle ear infection and throat infection. H e also has not emptied his bowels since yesterday. He is feeding well on breastmilk and taking solids. [/INST] Hi...by what you say I feel that it could be a seizure or it could be that he is straining at stools. But what ever it is - to be sure, please take a video of the episode when it occurs next time and consult your kid's pediatrician regarding this.Regards - Dr. Sumanth </s>
