A few Web sites I've found to be helpful:
Diary of New Mom
Annie's Eats - GREAT food recipes Web site! She's also a mom of two, so she blogs about her kids sometimes. Cool party ideas on here, too.
Wholesome Baby Food - GREAT resource on making your own baby food.
Baby Center - TONS of info on here about almost any topic you could imagine.
And they have a new blog- http://blogs.babycenter.com/
Lots of good info here and discussion boards, loved those!
I am sure I'll find more as I keep researching for answers to my own questions, so I'll post them on here when I find them! Let me know of others you have found.
