I'm sorry I have no advice on the LP surgery, but just wanted to welcome you to YT and tell you how sweet your little boy looks! (What's his name by the way?).
There are so many knowledgable people here on YT. You've come to the right place and I'm sure lots of help will be chiming in soon. Sending well wishes to your little guy for a speedy recovery!!
(Also, LOVE your screen name - too funny.
