It will be passed in stools undigested but you will have to watch for 3-4 days.... Pl keep safety as this is 2nd time.... Sometimes it may cause trouble also...

Absolutely correct, keep small objects like battery, coins, pins etc out of site, they are curious and they will put most things into mouth

Hi.. My self Dr kirti Prajapati.. Practicing as a pediatric surgeon. Swallowing a date seed doesn't cause any problem as it will pass undigested in stool.  But you have to be careful that your kid should not be given or should be away from such small things as that may cause choking hazard... That is instead of seed going into food pipe.. It goes to wind pipe... And that can cause emergency situation. So up-to 4 yrs of age kids should be kept away from such small things like seeds... Nuts... Etc...
