mine wasent as active a few hours after...but def try drinking something cold and see if the lil one gets to movin

I got the TDAP shot too. I can't remember if he was really active that night but I didn't feel good the night I got. Try drinking orange juice or even ice water and that might get him to move. I wouldn't worry too much but if you are really concerned I would call your dr that's what they are there for!
