S.T.
I am actually in two moms groups from meetup.com - they are big groups and offer lots of different opportunities to meet other moms. I know there are a few groups in the aurora area for first time moms of infants/those expecting. You could probably find a group perfect for where you are located and what you need - to connect with other moms who are also new to motherhood or could offer some great information and advise!
It was kind of weird for me at first - not knowing anyone - but I am SO glad I did. I have met a lot of other women/kids, but have truly met a few really good friends. Give it a shot. No harm in trying.
Good luck and congratulations on the new baby. What an exciting adventure you are now on!
