We didn't keep a journal but I did write him a letter that he'll get to see in 17 years or so
Good idea about not buying everything right now...you need to see how big the little tyke is! DS was 8lbs 5oz at birth and then just turned into a little giant!

He quickly hit the 90-95 percentile for height and weight in a matter of days! As one doc put it "I can tell this one has never missed a meal!

"
IIRC you're looking at a newborn? Depending on the hospital, they'll make a mommy room available to you as the prospective adoptive parents...BY ALL MEANS make use of it! And if they don't offer one automatically, ask about it.
Also, make sure you are on the
same page now about circumsicion if it's a boy...and be prepared to communicate that to your counselor/hospital/birthmom as soon as you are notified! DW's cousin had a baby boy and they brought him to her in the mommy room a few hours after delivery...they had already done it!

She doesn't remember signing anything to have it done nor does her DH. But evidently that hospital still does it as a matter of practice

and you pretty much have to threaten them with legal action to NOT have it done! Our DS' hospital, by contrast, waits until Day 2 or 3 and then asks if the procedure is to be done or not
Not to scare you but be aware of the vibes you send out because whenever a nurse or hospital social worker comes to check on you & baby, they'll make a note of it in the baby's file!

"Parents feeding baby" "Baby changed at 0915, wet diaper, parents did changing" "Parents seem nervous/scared/totally at ease with baby"... As the discharge nurse told us, she has prevented several parents from leaving the hospital with a baby until they calmed down or perhaps even completed the baby training offered by the hospital!
And double-check your state's rules for baby seats. You'll have to have one before they even consider cutting off that "Don't steal me" sensor tag(s)!! We found out that even though some car seats (like the Britax convertibles) can accomodate kids from newborn to 3 years, some states
require you to use the infant carrier!
