just pick him up. he may need a bit of extra affection that he is not getting in day-care. when you are holding him he feels that you will not go away. after a few minutes just put him down and play with him as a distraction. this will eventually stop. you don't see parents carrying older kids around in most cases.
my 2 year-old wants to be picked up very often. should i pick him up when he requests this? . my son just turned 2 last month. he is in daycare during the week and when he is home with mom & dad he very often wants "up". then he often wants mom or dad to go "this way" or "that way". am i doing harm by indulging him by picking him up upon his request to be picked up often. i want to be affectionate but i am afraid this is not good for him in the long-run.
