Trying to meet new people

So I am a stay at home mom of a now 9 month old and I needed to start making mom friends for me and my daughter.  Good thing I live in an age where you can pretty easily find groups online.  I managed to join a couple of them so me and my little girl can meet new people and get out of the house.  Well, an obstacle I've just learned that I need to overcome is finding the perfect time of day to attend these things!  If you are a mom, then you know what I mean.  Right now my daughter naps twice a day and unfortunately most of these playdates are schedule right smack in the middle of her morning one which seems to be the most popular time!  Anyway, so far we've been able to finally get to one of them.  I met some new moms and found where there is a park near me.  Little by little I am getting acclimated to this new place.
