As Clocker said, the worst part of it is over. (We didn't have to deal with jaundice with our two, but know of many cases that it was quite severe).
Words of advise from my better half:
1. Trust your gut, and take everything anyone (whose not a medical professional) says to you with a grain of salt. Some of the crap my mum used to come out with, was truly scary. (Stuff they did back in 70's has found to be dangerous since). Be very aware of old-wives tales...
2. Do not compare the development of your child to any other child, they will all develop at different rates. The only thing to watch, is that they reach certain milestones by set ages. eg. don't care that little johnny could recite the alphabet and count in powers of two at 12mths, and while your child is happy just eating crayons at 12mths.
3. Be prepared for the crap you will hear in parents rooms. The stuff that I have heard me has certainly scared me for life! (No, I don't want to hear how you tore during delivery and needed internal and external stitches, or how your nipples bleed constantly during the time you breast feed, or how you husband hates your sagging belly, or... (and that's the nice stuff).
).
Also glad that you're home now, and family is able to assist and let the both of you get some rest.
