My oldest will be 4 on December 14th he loves birthday cards. He is down because he doesn't understand why his dad won't be here for his birthday. Who wants to send him a card to make him feel a little better? His favorite ones are the ones that play music my great grandma gave him one he plays with all the time

his name is robert but he goes by stewie or robbie.

he doesn't understand his dad lives in California and can't be here. (if he really wanted to he could but isn't going to) he doesn't even know if he's going to send him anything for his birthday.
