Hi and congrats on your new baby!! :-) :-)
my question is between the 4pm-6pm and the 6-8pm feeding I'm not sure what to do about napping.
I just looked up what Tracy says in the second book (BWSAYP). She recommends the following:
4pm feed
5.15pm catnap
6pm feed
7pm bath
7.30pm catnap
8pm feed
right back to bed.
So w/ that in mind i would say to not extend during that period. I not clear on what you mean when you he doesn't sleep, that will definitely lead to him being overtired and waking more at night.
As for the 7am start, i think at 8weeks you are expecting a wee bit too much of both of you. 6am isn't too far off a normal wake up time, so give it a bit more time. Then some moms have had success w/ having a set time to start the day - such as 7am.
