Sorry to hear about your daughter being sick. Hope she gets better soon. The vomit/change clothes and sheets back-and-forth can be pretty defeating.

As for what has shocked me so far:

• How little sleep you can operate on when you have to. I felt this most truly during the infancy stages.
• How kid's development skyrockets while leaving experiences rather than during them. For example, whenever my kids' cousins visit for a couple of days, it's not until just after they leave that my kids start saying or trying new things.
• How different boy and girl temperaments really are.
• How resilient they have made me. Adversities that I have experienced would have shaken me to my core before my kids, but they shifted my perspective so much that as long as they are okay, so am I.

I am very much enjoying the struggle :)
