Hi Carrie,
IF...if this is c then one thing I would suggest is letting the kids know that Mommy has an owie and might be a little sick and maybe even grumpy, but you will be ok in awhile and love them very much. Our kids were older; 13,11,and 9. We brought them to the center so they could see everything Dad would be going through. We made sure they understood that Dad might be sick for awhile but that it was actually to make him better. Your 4 year old won't understand that maybe, but your 7 year old might. It's just better to let them know it's ok that you're sick and that you will get better. It also offers great snuggle time when you're resting. The kids sat with Daddy and watched movies. Depending on tx, there might be a few times you'll need to not have them on your lap, but the docs will warn you.
But, let's just say you won't have to worry about any of it!!!
