Buy life insurance for your child. It is a good idea. You don't need to buy a huge policy, just one big enough to cover funeral expenses and any time you will take off of work.
I have lost a child. I speak from experience. There is no way I was going to go cheap on my son's final arrangements. If I had wanted his casket lined with baby blue silk, I would have had it done. You do not plan to lose a child, but when it happens, it is stunning. Not having to worry about bills is a very nice benefit.
Further, let me assure you, you do not want to have to go back to work right away. I know some parents who have, and some who have not been able to summon their strength to get out of bed for weeks and sometimes months. I came back to work immediately (8 days later). I would then go home, feed my three year old a bowl of cereal, crawl into bed and cry myself to sleep. I should have stayed home and taken care of myself. At least I had a choice. Many of the other parents I know did not. They had to be at work. This was regardless of night spent crying themselves to the point of vomitting or staring at a wall all night long.
Really, buy the insurance. Not for long term benefits of insurability, but for the piece of mind that it brings in knowing you can financially handle the unthinkable.
