I think it is great that your grandma can take care of your newborn for you while you are at work. It is normal to worry when you return to work. I suggest spending some time at your grandma's house seeing how she handles the other kids, to ease your worrry, because chances are she is going to do a great job. If you still feel the need to bring it up, you might start by sharing how emotional it is for you to leave your baby all day while you are at work. Then ease it to it carefully. Best of luck and congratulations on your baby.
