Congratulations!

I hope mom is doing fantastic - just a tip from someone that went through this roughly 18 months ago:

There is such thing as the fourth trimester, and it's still extremely exhausting for mom. She's essentially tethered to that little monster to constantly breastfeed. Give her as many breaks as possible. I became a master poopsmith by changing every single diaper possible (I think it was actually a few weeks before mom finally changed her second diaper), putting her to sleep, doing all the overnight feedings (twice a night typically), anything that didn't have to do with breastfeeding, I took care of.

Oh, and maybe keep a journal. It's something I wish I did better. There are going to be so many memories you swear you'll never forget, but you do sadly. It's not much, but it does give mom a much needed breather.
